A skydiver steps out of a plane and falls straight down towards the Earth. At some point, the force of air resistance is smaller in magnitude compared to the force of gravity acting on the skydiver. What will happen to the skydiver at this point? a) The skydiver will slow down as they move in the downward direction. b) The skydiver will speed up as they move in the upwards direction. c) The skydiver will maintain their current speed as they move in the downward direction. d) The skydiver will accelerate at exactly 9.80 m/s2 [down]. e) The skydiver will accelerate downwards at a rate that is less than 9.80 m/s2.
