10. A ski-jumper starts from rest at the top of the ramp and slides down towards the jump. After launching into the air he follows the trajectory shown until he lands and skids to rest. a. Draw a realistic energy bar chart showing what happens between the moment the skier is at rest at the top of the ramp (point A) and the moment the skier is just becoming airborne (point B). If any work or heat is being done explain the reason for it. State your system and zero level for gravitational potential energy. Keep these choices consistent through parts b. and c. below. b. Repeat part a. except show what happens between the moment the skier is just becoming airborne (point B) and the moment he lands (point C). c. Repeat part a. except show what happens between the moment the skier lands (point C) and the moment he at rest again (point D). 10.
