Gayle runs at a speed of 3.30 m/s and dives on a sled, initially at rest on the top of a frictionless snow-covered hill. After she has descended a vertical distance of 5.00 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 15.0 m? Gayle's mass is 46.0 kg, the sled has a mass of 5.05 kg and her brother has a mass of 30.0 kg.

An 18-kg sled starts up a 36 ∘ incline with a speed of 2.2 m/s . The coefficient of kinetic friction is μk= 0.25. How far up the incline does the sled travel? What condition must you put on the coefficient of static friction if the sled is not to get stuck at the point determined in Part A? If the sled slides back down, what is its speed when it returns to its starting point?
