Question

The potential energy of a ball at the top of a hill is 15,000 J. Two-thirds of the way down the hill, the potential energy is 5476 J. What is the ball's kinetic energy at

that point?

Answer 1

kinitic energy1 + potential energy1 = kinitic energy2+ potential energy2

15000+0=ke2+5476

ke2=15000-5476

ke2=9524

kinetic energy of the Bal at that point= 9524
