B. He’s released from rest so his velocity is zero giving him zero Kinetic energy.

B. He’s released from rest so his velocity is zero giving him zero Kinetic energy.

A. If we say that we are measuring potential energy with reference to the lowest point on the track, then at this point the skater has no potential energy but he’s moving so has Kinetic Energy. Since Friction is “off” there is no transfer to thermal.

D. He’s above the reference point of the lowest point on the track so he has gravitational potential energy and he’s still moving so he has kinetic energy.

D. He’s above the reference point of the lowest point on the track so he has gravitational potential energy and he’s still moving so he has kinetic energy. Even though this is a dip, he has Grav Potential with reference to the lowest point of the track which we said was our zero point.
