Offering 99 the gravitational pe (u) depends on three things: the object’s mass (m), its height (h), and gravitational acceleration (g), which is 9.81 m/s^2 on earth’s surface. set the mass of the car to 50.0 grams, then set the three hills to the following heights: hill 1 - 90.0 cm, hill 2 - 65.0 cm, hill 3 - 20.0 cm. calculate the difference in gravitational potential energy from the top of hill 1 to the top of hill 3. show all work.
