A long thin bar (length L = 18 cm, mass 1.8 kg) of uniform
density is placed upon a horizontal, frictionless surface. A small
rubber puck (mass 250 g) slides towards the bar with a speed (2
m/s) directed perpendicular to the bar. It collides perfectly
elastically with the bar at a distance (d) from the center of mass
of the bar in such a way that the puck rebounds with a velocity (1
m/s).

A baseball has a mass of 0.15 kg and radius 3.7 cm. In a baseball game, a pitcher throws the ball with a substantial spin so that it moves with an angular speed of 30 rad/s and a linear speed of 39 m/s. Assuming the baseball to be a uniform solid sphere, determine the rotational and translational kinetic energies of the ball in joules.

A grinding wheel is a uniform cylinder with a radius of 8.50 cm and a mass of 0.480 kg. Calculate the applied torque needed to accelerate it from rest to 1750 rpm in 5.10s.Take into account a frictional torque that has been measured to slow down the wheel from 1500 rpm to rest in 53.0s. Part A was to calculate the moment of inertia about its center. The answer was 1.73x10-3

2) A uniform solid ball has a mass of 20 g and a radius of 5 cm. It rests on a horizontal surface. A sharp force is applied to the ball in the horizontal direction 9 cm above the surface. The force rises linearly from 0 to a peak value of 40,000 N in 10-4 s and then decreases linearly to in another 10-4 s. (The moment of inertia for a solid ball ismR2) a) What is the velocity of...
