Gayle runs at a speed of 4.17 m/s and dives on a sled, which is
initially at rest on the top of a frictionless snow-covered hill.
After she has descended a vertical distance of 4.52 m, her brother,
who is initially at rest, hops on her back and together they
continue down the hill. What is their speed at the bottom of the
hill if the total vertical drop is 17.3 m? Gayle's mass is 52.8 kg,
the sled has a mass of 5.45 kg and her brother has a mass of 33.1
kg.
