A parachutist jumps from height 100 m He is to reach at ground with zero velocity For this purpose he switches on a parachute propeller after falling freely for certain height Given that after the parachute propeller is switched on total acceleration of the man varies with velocity as a 2v where v is the instantaneous velocity of the man Choose the correct options for this situation use g 10 m s a Man switches on parachute propeller after falling freely for time 4 second b Man switches on parachute propeller after falling freely for time 2 second c Distance covered by the man with parachute propeller switched on is 20 m d Distance covered by the man during free fall is 60 m
