EXAMPLE 1: GOLF BALL STRUCK B A golf ball of mass 50 g is struck with a
club. The force exerted by the club on the
ball varies from zero, at the instant before
contact, up to some maximum value and
then back to zero when the ball leaves the
club. Assuming that thc ball travels 200 m
and the launch angle is 45°, estimate the
magnitude of the impulse caused by the
collision
