skydiver of mass m jumps from a hot air balloon and falls a distance d before reaching a terminal velocity of magnitude v. Assume that the magnitude of the acceleration due to gravity is g. Part A What is the work Wd done on the skydiver, over the distance d, by the drag force of the air? Express the work in terms of d, v, m, and the magnitude of the acceleration due to gravity g. View Available Hint(s) Wd = nothing Part B Find the power Pd supplied by the drag force after the skydiver has reached terminal velocity v. Express the power in terms of quantities given in the problem introduction. View Available Hint(s) Pd = nothing Provide Feedback

the design of a ski jumping suit involves a trade-off between giving the skiers lift to get higher jumps and ensuring the skier does not face a lot of drag before the jump itself. an expansive suit may to lift the skier higher, but at the same time, it will also increase the air resistance. higher air resistance as the skier goes down the slope limits the speed of the jump. a big suit also increases the risk of losing balance or control, especially if there's a strong gust of wind. while technologically enhanced suits a lot, clothing is not the only factor in a ski jumper’s success. gathering speed while skiing down the slope, ensuring good speed on the ramp, and maintaining good body posture and form in the air all contribute to a ski jumper's success.
