3. A 65kg boy is skating with a velocity of 5m/s, if he pushes himself to slow down for a distance of 4m and reaches a final velocity of 2m/s, what force did he apply?

Submit the answer to this question in today’s assignment.

According to newton’s first law of motion, which force is expected to cause a body to accelerate?

The substances that are necessary for producing of certain hormones and that store and transport vitamins

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?
