Question

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?

Use the conservation ofmomentum to solve for one veloicty in terms of the other. then put that into the conservation of energy equation.
