hello this is about collisions in physics. i already solved all of them but i just want to make sure im correct. can you pls help me solve 1-5? thanks

1. A golf ball with mass 0.556 kg, is dropped from a some height above the ground. The golf ball experiences a perfectly elastic collision with the ground, meaning that the final momentum has the same magnitude as the initial momentum. If the velocity reaches a maximum of 3.68 m/s just before it reaches the ground, what is the momentum of the golf ball at that moment? 2. If the bat exerts a force of 1,607 N as it collides with the baseball of mass 0.181 kg, and the collision lasts for 0.039 seconds, how much force does the ball exert on the bat? (Magnitude only--no negatives) 3. A golf ball of mass 0.183 kg is dropped from some height above the ground. It experiences a perfectly elastic collision with the ground, meaning that the final momentum has the same magnitude as the initial momentum. If the momentum of the golf ball just before it hits the ground is 0.682 kg m/s , what is the change in momentum (impulse) the ball experiences? (direction matters) 4.Suppose that the golf ball was in contact with the floor for 0.01 seconds. If the change in momentum of the ball was, -0.559 kg m/s , what is the net force on the ball while it was in contact with the floor? 5. While being thrown, a net force of 185 N acts on a baseball of mass 0.101 kg for a time of 0.039 seconds. What is the change in momentum of the ball
