Question

Consider a situation where the disk has a mass of 51.0 g and an initial velocity of 35.0 m/s when it strikes the stick that is 1.25 m long and 2.25 kg at a distance of 0.100 m from the nail.

A. What is the angular velocity (in rad/s) of the two after the collision? (Enter the magnitude.)

B. What is the kinetic energy (in J) before and after the collision?

K_before =

K_after =

C. What is the total linear momentum (in kg · m/s) before and after the collision? (Enter the magnitude.)

p_before =

p_after =
