Q1. A hollow spherical shell has mass 8.00 and radius 0.225. It is originally at rest and then rotates about a stationary axis that lies along a diameter with the constant acceleration of 0.905. What is the kinetic energy of the shell after it has turned through 6.50?

Q2. A 0.280 kg croquet ball makes an elastic head-on collision with a second ball firstly at rest. The second ball moves off with half the original speed of the first ball.

(a) What is the mass of second ball?

(b) What fraction of original kinetic energy (ΔKE/KE) gets transferred to the second ball?
