A 2.0-g particle moving at 5.2 mj's makes a perfectly elastic head-on collision with a resting l.CI-g object. {a} Find the speed of each particle after the collision. (b) Find the speed of each particle after the collision if the stationary particle has a mass of 10 g. {c} Find the final kinetic energy of the incident 2.0-g particle in the situations described in parts (a) and (ts). paw :1 paw :1 In which case does the incident particle lose more kinetic energy? 0 case (a) 0 case [b]
