5054Friction

A free-fall skydiver jumps from a plane. As he falls there is a force acting upwards and a force acting downwards on his body. These produce a resultant force. Before he reaches terminal velocity, how do the sizes of the forces change?

  1. Adownward force decreases; upward force decreases; resultant force stays the same
  2. Bdownward force increases; upward force stays the same; resultant force decreases
  3. Cdownward force stays the same; upward force increases; resultant force decreases
  4. Ddownward force stays the same; upward force increases; resultant force increases
