Question

What is the mass of an object if its height is 10 meters above ground and its gravitational potential energy (GPE) is 3920 Joules? Remember Gravity = 9.8 meters per seconds squared

Answer 1

Answer:

The net work on the roller coaster is then done by gravity alone. The loss of gravitational potential energy from moving downward through a distance h equals the gain in kinetic energy. This can be written in equation form as −ΔPEg = ΔKE.
