A man with a mass of 60 kg skis down a frictionless hill that is h = 2.2 m high. At the bottom of the hill the terrain levels out. As the man reaches the horizontal section, he grabs a 20-kg backpack and skis off a 2.0-m-high ledge. At what horizontal distance from the edge of the ledge does the man land?
Someone will gladly critique your thoughts.
