Question 6 (Mandatory) (10 points)
In this lab, we see that ◻
a) since mechanical energy is not conserved, all the potential energy is lost to the environment
b) since mechanical energy is conserved, all the potential energy at the top of the track, is converted to kinetic energy at the bottom of the track
c) since mechanical energy is conserved, all the kinetic energy is converted to thermal energy
d) since mechanical energy is not conserved, the speed of the skater is not related to the kinetic energy
