A skydiver leaves an aeroplane and, after a few seconds, attains terminal velocity without deploying his parachute. Why does he attain 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.
