Question

Gayle runs at a speed of 4.00 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 they continue down
the hill together. What is their speed at the bottom of the hill
if the total vertical drop is 15.0 m? Gayle’s mass is 50.0 kg,
the sled has a mass of 5.00 kg, and her brother has a mass of
30.0 kg.
