A basketball mith a mass of 0.62kg falls vertically to the floor where it hits with a speed of -6 m/s. (we take the positive direction to be upward here.) The ball rebounds, leaving the floor with a speed of 4.5 m/s. A) What impulse acts on the ball during its collision with the floor? B) If the ball is in contact with the floor for 0.04 s, what is the average force of the ball on the floor?
