A skydiver weighing 910 N opens his parachute at the appropriate height
from the ground. The air exerts a significant upward drag force, which is
initially greater than the weight of the diver. This helps to slow the skydiver
down. What is the diver's acceleration (both direction and magnitude in
m/s?) if the magnitude of the drag force is 1165 N?

During a circus act, one performer swings upside down hanging from a
trapeze holding another, also upside-down, performer by the legs. If the
upward force on the lower performer is three times her weight, how much
(in m) do the bones (the femurs) in her upper legs stretch? You may assume
each is equivalent to a uniform rod 30.0 cm long and 1.88 cm in radius. Her
mass is 55.0 kg.
