A person jumped out of a plane and began falling to the surface of the Earth at a rate of 9.8 m/s².The person and their equipment have a total mass of 95 kg.After 30 seconds they have reached a speed of 50 m/s.Calculate the kinetic energy store of the person and their equipment at this moment.KE = _____ J

A person jumped out of a plane and began falling to the surface of the Earth at a rate of 9.8 m/s².The person and their equipment have a total mass of 95 kg.After 30 seconds they have reached a speed of 50 m/s with a kinetic energy store of energy of 118 750 J.During this fall the person has had a change in gravitational energy of 2.3 MJ.Calculate the energy transferred to the surroundings.

An object is released from rest in a vacuum at a height H above the Earth’s surface.As the object falls it passes a point at a height of 0.75H above the surface.What is kinetic energy of the object at a height of 0.75gravitatiHoonal potential energy of the object at a height of H

The ball has a mass of 1.9 kg and is 2 m off the ground.If it currently has 30 J of kinetic energy, what will be the total amount of kinetic energy stored in the ball the moment it hits the ground?Gravitational field strength on Earth is 9.8 N/kg.Ignore the effects of air resistance.You must include units in your answer.

A 90.0 kg person is sitting in a 100 kg boat, which is floating at rest on a lake. In the boat is a stone with a mass of 5.00 kg. The person throws the stone at 4.00 m/s horizontally in the NORTH direction. The kinetic energy of the boat and person after throwing the stone is

Shawn and his bike have a total mass of 45.5 kg. Shawn rides his bike 1.95 km in 10.0 min at a constant velocity. What is Shawn's kinetic energy? Assume that air resistance is negligible.
