A 1.5-kg playground ball is moving with a velocity of 3.0 m/s directed 30o below the horizontal just before it strikes a horizontal surface. The ball leaves this surface 0.50 s later with a velocity of 2.0 m/s directed 60o above the horizontal. What is the magnitude of the average resultant force on the ball?
