If a rock is falling with a speed of 20 m/s and has 200 J of kinetic energy. What is the mass? 20 kg b. 10 kg d. .1 kg a. 1 kg C.

if a star is moving toward earth, its light waves appear to be squeezed together. hope it

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
