A car has a mass of 2,000kg and is traveling at 28 meters per second what is the car's kinetic energy

How can i calculate the net force of an object?

An object of mass 200 kg is released from rest from a boat into the water and allowed to sink. While gravity is pulling the object down, a buoyancy force of StartFraction 1 Over 40 EndFraction times the weight of the object is pushing the object up
