Answer:7.5

Explanation:Answer:The the average magnitude of the force exerted on the ball by the floorNExplanation:Given:

Mass of ball kg

Initial speed

Rebound speed

Contact time interval sec

For finding the average magnitude of the force on the ball by the floor is given by,Here

N

Therefore, the the average magnitude of the force exerted on the ball by the floorN
