What constant force does the punter exert on the ball?

  1. Feb 5, 2004 #1
    Could someone help me with this problem?

    A football punter accelerates a 0.55kg football from rest to a speed of 8.0 m/s in 0.25s. What constant force does the punter exert on the ball?

    The force I got was 19.7 N. Is this right?

    17.6 no?

    f = ma

    f = ?
    m = 0.55
    a = 32 -> 4*8=32

    f = 0.55*32
    f = 17.6N
