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