Physics problem be !
explain in detail what occurs within the following scenario using concepts of 2-dimensional; motion, force, energy, and conservation of momentum.
scenario:
a ball that has an initial horizontal velocity is knocked off a desk. it strikes the floor below and continues to bounce with the same initial direction before finally coming to rest.

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?
