Two particles are undergoing elastic collisions. Particle A has a mass 0.2 g moving with a speed of 5.0 ntF's undergoes headon collision with particle B of mass 0.8 g, which is initially at rest. [a] "What are the final velocities of the two particles A and B after the collision? (In) If the contact time is 0.050 s= what was the average force on the particle A and on particle B. (ImpulseMomentum) (c) You are playing indoor sand handball and it is traveling toward you. Which action will require a greater force on the hand hall= your catching the hall or your hitting the hall hack?r (3 points)
