Gayle runs at a speed of 8.00 m/s and dives on a sled, initially at rest on the top of a frictionless, snowcovered hill, that has a vertical drop of 14.0 m. After she has descended a vertical distance of 5.00 m, her brother, who is initially at rest, hops on her back, and they continue down the hill together. (a) What is the sled’s speed just after jumping on the sled?
Gayle’s mass is 47.0 kg, the sled has a mass of 6.00 kg, and her brother has a mass of 35.0 kg.

7.09 m/s
