A parachutist after bailing out falls 50 m without friction. When parachute opens, it decelerates at\[2m/{{s}^{2}}\]. He peaches the ground with a speed of 3 m/s. At what height, did he bail out?
AIEEE Solved Paper-2005
A)91 m
B) 182 m
C)293 m
D) 111 m
Correct Answer:
C
Solution :
Parachute bails out at height H from ground velocity at A The velocity at ground (given) Acceleration (given) \[H=242.75+h=242.75+50\approx 293\,m\]
