Gayle runs at a speed of 4.70 m/s and dives on a sled, initially atrest on the top of a frictionless snow covered hill. After she hasdescended a vertical distance of 5.00m, her brother, who isinitially at rest, hops on her back and together they continue downthe hill. What is their speed at the bottom of the hill if thetotal vertical drop is 18.5m? Gayle's mass is 50.0kg, the sled hasa mass of 5.00kg and her brother has a mass of 30.0kg.
This is similar to homework problem 31, chapter 6, college physicsvolume 1. I have tried it 4 times and keep getting it wrong. Pleasehelp!
