A baseball is traveling with velocity v and then is caught by a glove. Which of the following statements is true? This is an elastic collision.

This is an inelastic collision.

The impulse of the glove catching the ball is F/t.

The glove and the ball travel independently after the collision.

Aballoon is rising vertically upwards at a velocity of 10m/s. when it is at a height of 45m from the ground, a parachute bails out from it. after 3s he opens his parachute and decelerates ata a constant rate 5m/s.when. (a) what was the height of the parachutist above the ground when he opened his parachute? (b)how far is the parachutist from the balloon at t=3s? (c)with what velocity does the parachutist hit the ground? (d)after how long does the parachutist hit the ground after his exist from the balloon?
