Suppose you start an antique car by exerting a force of $300 \mathrm{N}$ on its crank for 0.250 s. What is the angular momentum given to the engine if the handle of the crank is $0.300 \mathrm{m}$ from the pivot and the force is exerted to create maximum torque the entire time?

Given the following data for a fire extinguisher-toy wagon rocket experiment, calculate the average exhaust velocity of the gases expelled from the extinguisher. Starting from rest, the final velocity is $10.0 \mathrm{m} / \mathrm{s}$. The total mass is initially $75.0 \mathrm{kg}$ and is $70.0 \mathrm{kg}$ after the extinguisher is fired.

You have a horizontal grindstone (a disk) that is 86 kg, has a 0.38 m radius, is turning at 89 rpm (in the positive direction), and you press a steel axe against the edge with a force of 23 N in the radial direction. Assuming that the kinetic coefficient of friction between steel and stone is 0.20, calculate the angular acceleration of the grindstone in rad/s2. What is the number of turns, N, that the stone will make before coming to rest?

A car of mass m = 1150 kg is traveling down a θ = 12 degree incline. When the car's speed is v0 = 15 m/s, a mechanical failure causes all four of its brakes to lock. The coefficient of kinetic friction between the tires and road is μk = 0.45.Calculate the distance the car travels down the hill L in meters until it comes to a stop at the end.
