A 0.565-kg ball has an elastic, head-on collision with a second ball that is initially at rest. The second ball moves off with half the original speed of the first ball.
(a) What is the mass of the second ball?
(b) What fraction of the original kinetic energy (?K/K) is transferred to the second ball?
Three insulating balls are suspended from thin threads. Various objects are then rubbed against other objects and each of the insulating balls is charged by touching them with one of these objects. In each case.
