Homework Help: Impulse word problem

  1. Mar 2, 2012 #1
    1. The problem statement, all variables and given/known data
    A 12.5 ball traveling at a speed of 32.4 m/s strikes a wall and rebounds with the same speed. What is the impulse exerted by the wall on the ball?

    Part II A 12.5 g ball is traveling at a speed 3.4 m/s strikes the center of a 29.5 g ball of the same radius. The balls are in contact for 43.1 milliseconds and the first ball rebounds with a loss of 20% of its speed. What is the impulse exerted by the second ball on the first? B) What is the momentum of the second ball after the collision

    2. Relevant equations
