Answer
(a) Both objects have the same change in momentum.
(b) The object with the smaller mass has the greatest change in velocity.
(c) The object with the smaller mass has the greatest acceleration.
Work Step by Step
(a) Since the change in momentum is $Force \times Time$, both objects have the same change in momentum.
(b) The change in velocity is the change in momentum divided by the object's mass. Since the momentum change is the same for both objects, the object with the smaller mass has the greatest change in velocity.
(c) According to Newton's second law: $F = ma$
Since the applied force is the same for both objects, the object with the smaller mass has the greatest acceleration.
