freebody: after she jumps: gravity down.
in one min: gravity down, air resistance up
if she is at constant speed, acceleration is zero, and her friction is equal to her weight.
A skydiver [m=95kg] jumps out of an airplane and opens her parachute 45 seconds later. After another 15 seconds, the skydiver begins to descend gently at a constant speed of 7.8m/s. Draw a freebody diagram of the skydiver just after she's jumped out the airplane AND 1 minute after she has jumped out. Calculate the acceleration and the force of friction on the skydiver after she's fallen for 1 minute.
