A 81.6 kg snowboarder is on top of a hill that has an elevation of 127
meters. If she heads straight down the hill without slowing down and if
we assume that she encounters no frictional forces on the way down,
answer the following:
11. What is the gravitational potential energy of the skier at the top
of the hill?
12. What is the kinetic energy at that point?
13. What is the gravitational potential energy at the bottom of the hill?
14. What is the kinetic energy at the bottom of the hill?
15. How fast will she be going at the bottom of the hill?
16. What is her total energy at any time on the hill?
