Asked by Micheal
A ball has a potential energy of 180 J and a kinetic energy of 0 J. After falling 2m, it has a potential energy of 135J. What is its kinetic energy at this point?
PLEASE ANSWER THIS I'M STUCK!

Assuming energy is conserved, gravitational potential energy and kinetic energy 'swap' during a fall, and the numeric values transfer. I would say the answer is 180 - 135 = 45J
Kinetic energy = 45J
Kinetic energy = 45J
