An 80 kg swimmer steps off a platform 10 m above the waterand free-fallsdownward. Onceshe entersthe water, drag forcestake over andbring her to rest in 3.0 s (after her feet first touch water). (a) Assuming that the drag force is constant, find this force. (b) Find her depth under the water when she comes to rest.

    Please explain steps: An 80 kg swimmer steps off a platform 10 m above the water and free-falls downward. Once she enters the water, drag forces take over and bring her to rest in 3.0 s (after her feet first touch water). (a)Assuming that the drag force is constant, find this force. (b) Find her depth under the water when she comes to rest.

    4. A 90 kg rocket stuntman steps off of a platform that is 50 m above the ground (and he therefore starts at rest). While he is descending, his rocket pack exerts a steady upward force of 800 N. Ignore air resistance. (a) What is the magnitude and direction of the net force on the stuntman? (b) What is his acceleration? (c) How long does it take him to reach the ground? (d) What is his speed when he reaches...
