Homework Help: Force of impact?

  1. Oct 12, 2004 #1
    A golf ball (m = 38.6 g) is struck a blow that
    makes an angle of 46.3 degrees with the horizontal.
    The drive lands 273 m away on a flat fairway.
    The acceleration of gravity is 9.8 m/s^2 .
    If the golf club and ball are in contact for
    10.2 ms, what is the average force of impact?
    Neglect air resistance. Answer in units of N.
    I found the velocity, where do I go from here?

    Force is change in momentum per unit time!
