A skydiver is dropped out of an airplane. Her weight is 650 Neetons.  a. The skydiver free-falls and then she opend her parachute, from that point on she falls with a constant speed of 8.00 m/s. Determine her momentum (magnitue and direction) the instant before she hits the ground.  b. Her impact with the ground occurs over a period of 0.0800 seconds afterwards she is at rest. Determine the force of the ground on the skydiver (magnitude and direction).  c. Determine the force of the skydiver on the ground (magnitude and direction). Explain!
