A 1.5kg 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?

Divide the magnitude of the momentum changr by 0.50 s. You will need to compute both the horizontal and vertical components of the momentum change.
