A 0.24-kg object traveling rightward at 3.5 m/s collides head-on and elastically with a 0.40-kg object traveling leftward at 2.1 m/s. (a) what are their velocities after collision? (b) If the objects are in contact for 0.010 s during collision, what is the magnitude of the average forcethey exert on each other?
