Magnitude of Avg Force

  1. Dec 10, 2006 #1
    A 0.7 kg basketball is rolling by you at 3.5 m/s. As it goes by, you give it a quick kick perpendicular to its path. Your foot is in contact with the ball for 0.003 s. The ball eventually rolls at an angle of theta = 30 degrees from its original direction.
    Determine the magnitude of the average force you applied to the ball.

    Not sure how to do this, im using the momentum principle and its not working
