Question

A parachutist after bailing out falls 50 m without friction. When parachute opens, it decelerates at $2\frac{m}{s^2}$. He reaches the ground with a speed of $3\frac{m}{s}$. At what height, did he bail out ?

• A. 293 m
• B. 111 m
• C. 91 m
• D. 182 m

Answer 1

The correct option is A 293 m

At point B, parachute opens and it moves with retardation of $2\frac{m}{s^2}$ and reach at ground (Point C) with velocity of $3\frac{m}{s}$
