Problem Set 5C: A child and sled with a combined mass of 52.1 kg slide down a frictionless hill. Assuming that they
start at rest (v; = 0) and they are on Earth (g = 9.81m), calculate the initial height (hi) if their final speed (vf) is
12.3 m/s at the bottom of the hill (hj = 0).
The calculated answer is
Please do not include units and
round answer to ONE place after the decimal.
