What is the magnitude of the impulse

  1. Apr 7, 2014 #1
    1. The problem statement, all variables and given/known data
    a ball having a mass of 150 g strikes a wall with a speed of 5.2 m/s and rebounds with only 50% of its initial kinetic energy. what is the magnitude of the impulse on the wall from the ball?


    2. Relevant equations
    I=Ft
    I=ΔP
    KE= 1/2 m v^2


    3. The attempt at a solution
    the answer is 1.3 N s but i dont know how to get there.

    What was its kinetic energy before hitting the wall? What was its kinetic energy after rebounding?
