5054Friction
A skydiver jumps from an aeroplane. After a few seconds, he reaches a terminal velocity without opening his parachute. Why does he reach terminal velocity?
- AAir resistance becomes greater than his weight and slows him down.
- BAir resistance decreases and he speeds up.
- CAir resistance increases and balances his weight so that his acceleration is zero.
- DHis weight decreases and balances the air resistance.
