A parachutist after bailing out falls 50 m without friction When parachute opens, he descends at 2 ms and reaches the ground with a speed of 3 m l At what height did he bailout ?

A

191 m

B

182 m

C

293 m

D

111 m

Text Solution

Verified by Experts

The correct Answer is:
c
For free fall `v^(2)=2xx9.8 xx50=980`
When parachute opens
`3^(2)=v^(2)-2xx2xxh`
4h=980-9 or `h=(971)/(4)`
Total height `=(971)/(4)+50=(1171)/(4)prop 293 m`
