A 100 g (mass) bouncy ball has a downward velocity of 10 m/s right before hitting the ground. Right after bouncing it has an upward velocity of 5 m/s. The average force on the bouncy ball when it is in contact with the ground is 150 N ( +y^). How long was the ball in contact with the ground to the nearest second. Show all work.
