A ball with a mass of 275 g is dropped from rest, hits the floor, and rebounds upward. If the ball hits the floor with a speed of 3.12 m/s, rebounds with a speed of 1.89 m/s, and is in contact with the floor for 1.20 ms, determine the following.
(a) magnitude of the change in the ball's momentum (Let up be in the positive ĵ direction.) kg · m/s
(b) change in the magnitude of the ball's momentum (Let negative values indicate a decrease in magnitude.) kg · m/s
(c) average force the floor exerts on the ball during their interaction (Use vector notation.) Favg = N
