A fisherman is holding a fishing rod with a large fish hanging from thee line. Identify the forces acting on the rod and describe the interaction partner of each.

The net force acting on the crate is determined as 176 N to the left.

The net force acting on the crate is calculated as follows;

∑F = F1 + F2 + F3 + F4

F(net) = -440y + 176x + 440y - 352x

F(net) = -176 x

The resultant force is pointing in negative x direction.

Thus, the net force acting on the crate is determined as 176 N to the left.

Explanation:

Final velocity of Jeff's car is 7.133 m/s south. The direction is 59.3° south of east.

In this issue, we can utilize preservation of energy to track down the last speed and course of Jeff's crash mobile after the impact with Julia's. Before the impact, the energy in the x-heading is zero, and in the y-course, it is 60 kg × 4 m/s = 240 kg⋅m/s north. Julia's force is 45 kg × 6 m/s = 270 kg⋅m/s west.After the crash, the energy in the x-course is rationed. The absolute energy in the x-course is as yet zero, as Julia's force that way is likewise zero. In the y-heading, the absolute force after the crash is 60 kg × vj + 45 kg × 2 m/s sin 15°, where vj is Jeff's last speed in the y-course.Utilizing protection of energy, we can compare the force when the crash in the y-heading:

60 kg × 4 m/s + 45 kg × 6 m/s = 60 kg × vj + 45 kg × 2 m/s sin 15°

Working on this situation, we get:

240 kg⋅m/s + 270 kg⋅m/s = 60 kg × vj + 12.19 kg⋅m/s

Addressing for vj, we get:

vj = (240 kg⋅m/s + 270 kg⋅m/s - 12.19 kg⋅m/s)/60 kg

vj = 7.133 m/s south

Consequently, Jeff's last speed is 7.133 m/s south. To find the course, we can utilize geometry. The point of Jeff's last speed concerning the x-pivot is given by:

θ = tan^-1(vj/4 m/s)

θ = 59.3° south of east

Accordingly, the last speed and heading of Jeff's amusement cart are 7.133 m/s at a point of 59.3° south of east.

(a) The angular acceleration of the grinding wheel as it came to rest is approximately -0.008 rad/s² (clockwise).

(b) The wheel made approximately 1000 revolutions during the time it was coming to rest.

(a) We can use the formula of rotational kinematics:

ω = ω₀ + αt

where ω is the final angular velocity, ω₀ is the initial angular velocity, α is the angular acceleration, and t is the time.

Given:

ω = 0 rad/s (final angular velocity)

ω₀ = 20.0 revolutions per second = 20.0 * 2π rad/s (initial angular velocity)

t = 50.0 s

Substituting the values into the formula, we have:

0 = 20.0 * 2π + α * 50.0

Solving for α, we get:

α ≈ -0.008 rad/s² (clockwise)

(b) To find the number of revolutions the wheel made during the time it was coming to rest, we can use the formula:

θ = ω₀t + 0.5αt²

where θ is the angular displacement.

Given:

ω₀ = 20.0 revolutions per second = 20.0 * 2π rad/s (initial angular velocity)

t = 50.0 s

α ≈ -0.008 rad/s² (clockwise)

Substituting the values into the formula, we have:

θ = (20.0 * 2π) * 50.0 + 0.5 * (-0.008) * (50.0)²

Simplifying the equation, we find:

θ ≈ 1000 revolutions

Therefore, the wheel made approximately 1000 revolutions during the time it was coming to rest.

Explanation:

There is more friction on the carpet creating more heat and energy loss. Potential energy is gained from being at a higher elevation.

The speed of the 1.0. kg mass at the equilibrium position is 2 m/s.

In physics, simple harmonic motion is the repeated back-and-forth movement through an equilibrium, or center, position so that the maximum displacement on one side of this position is equal to the maximum displacement on the other. Each whole vibration occurs at the same time interval.

A point mass performing a straightforward harmonic movement has an instantaneous velocity given by:

v(t) = ω × A × cos(ωt + Ф)

ω = Angular frequency

A = Amplitude

Ф = Initial phase

10cm × 1m / 100cm = 0.1 m

ω = √k/m

ω = √1/400

ω = 20

Ф = 0

v = (20) × (0.1) cos (20 × 0 + 0)

v = 2 × 1 m/s

v = 2m/s

Answer:

because the side walk is at high temperature

So, the current when the capacitor has acquired 1/4 of its maximum charge is approximately 0.171 A.

To find the current when the capacitor has acquired 1/4 of its maximum charge, we can use the equation for the current in an RC circuit, which is:

I(t) = V/R * e^(-t/RC)

Here,
I(t) is the current at time t,
V is the battery voltage (12.0 V),
R is the resistor value (14.0 Ω),
C is the capacitor value (1.30 µF),
t is the time when the capacitor has acquired 1/4 of its maximum charge, and
e is Euler's number (approximately 2.718).

First, we need to find the time t when the capacitor has 1/4 of its maximum charge. We can use the equation for the voltage across a charging capacitor:

V(t) = V * (1 - e^(-t/RC))

We know that at 1/4 of its maximum charge, the voltage across the capacitor will be 1/4 of the battery voltage:

V(t) = 0.25 * V = 0.25 * 12 = 3.0 V

Now, we can solve for t:

3.0 V = 12 V * (1 - e^(-t/(14 Ω * 1.30 µF)))

0.25 = 1 - e^(-t/(14 Ω * 1.30 µF))

0.75 = e^(-t/(14 Ω * 1.30 µF))

Now, take the natural logarithm of both sides:

ln(0.75) = -t/(14 Ω * 1.30 µF)

Now, solve for t:

t ≈ 3.14 * 10^(-6) s

Now, we can plug the value of t back into the current equation:

I(t) = 12 V / 14 Ω * e^(-3.14 * 10^(-6) s / (14 Ω * 1.30 µF))

I(t) ≈ 0.857 A * e^(-1.614)

I(t) ≈ 0.857 A * 0.199

I(t) ≈ 0.171 A

So, the current when the capacitor has acquired 1/4 of its maximum charge is approximately 0.171 A.

Explanation:

Because it reaches maximum height

A child sleds down a steep, snow-covered hill with an acceleration of 2.82m/s squared. if her initial speed is 0.0 m/s and her final speed is 15.5 m/s, It takes the child 5.50 seconds to travel from the top of the hill to the bottom.

We can use the following kinematic equation to solve this problem:

v^2 = u^2 + 2as

Where:

v is the final speed

u is the initial speed

a is the acceleration

s is the distance traveled

We are given u = 0.0 m/s, a = 2.82 m/s^2, and v = 15.5 m/s. We need to find s.

Rearranging the equation gives:

s = (v^2 - u^2) / (2a)

Substituting the values gives:

s = (15.5^2 - 0.0^2) / (2 x 2.82) = 74.47 m

Now, we can use another kinematic equation to find the time taken:

v = u + at

Where t is the time taken.

Substituting the values gives:

15.5 = 0.0 + 2.82t

Solving for t gives:

t = 15.5 / 2.82 = 5.50 seconds

False. The equation you provided, f = ddtddt(mv), is the correct equation for the force acting on an object (such as a rocket) with varying mass.

However, the assumption of constant mass (dm/dt = 0) cannot be applied to rockets as they experience mass change due to fuel consumption. In the case of a rocket, as it expels its exhaust gases, its mass decreases over time.

Therefore, the mass term (m) in the equation f = ddtddt(mv) is not constant and should be taken into account when calculating the force and acceleration of the rocket. This is typically done using the rocket equation, which incorporates the concept of mass change and the specific impulse of the rocket's engine.

The drift velocity of electrons in the wire is \(6.5 x 10^{-5} m/s.\) It can be calculated by using drift velocity formula.

The drift velocity of electrons in a wire of diameter 2.7mm that carries a current of 3 A can be calculated using the formula:

Drift velocity = I/(n.A.e)

Where I is the current, n is the number of charge carriers per unit volume, A is the cross-sectional area of the wire, and e is the charge of an electron. Given that the diameter of the wire is 2.7mm, we can calculate the cross-sectional area as:

A =\(\pi r^2 = \pi (1.35mm)^2 = 5.73mm^2\)

Now, we can plug in the given values into the formula:

Drift velocity = \(3 A/(n . 5.73mm^2 . 1.6 . 10^{-19} C)\)

Assuming that the number of charge carriers per unit volume is 8.5 × 10^28 m^-3, we can calculate the drift velocity as:

Drift velocity = \(3 A/(8.5 . 10^{28} m^{-3} . 5.73 . 10^{-6} m^2 . 1.6 . 10^{-19} C) = 6.5 . 10^{-5} m/s\)
