On earth, the gravitational potential energy of a ball is 1881 J. If the same 32 kg ball was given the same amount of gravitational potential energy as on earth how high would it have to be above the surface? (Moons g= 3.7m/s

answer: he got 23

explanation:

the motion of a pendulum is a classic example of mechanical energy conservation. a pendulum consists of a mass (known as a bob ) attached by a string to a pivot point. as the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion.
