A simple marble is placed at the top of a hill. The initial potential energy of the marble is 550 J. The marble slides down the hill. You take a picture of the marble at some point as it is down the hill. Without knowing the speed, the mass or the position of the marble, which of the following could be the only possible correct energies of the marble at this point? Assume no friction
Potential Energy = 310 J, Kinetic Energy = 180 J
Potential Energy = 140 J, Kinetic Energy 450 J
Potential Energy = 290 J, Kinetic Energy = 260 J
Potential Energy = 210 J, Kinetic Energy = 305 J
