Homework Help: A football punter accelerates a 0.56kg football

  1. Oct 29, 2003 #1
    A football punter accelerates a 0.56kg football from rest to a speed of 8.2 m/s in 0.24s.
    What constant force does the punter exert on the ball? Answer in units of N.
    Note: Is the answer 19.13333333N? I used the impulse-momentum theorem where m was 0.56kg and vf=8.2m/s and vi=0m/s, in addition delta t is 0.24s.
