Question

A parachuitist of weight W strikes the ground with his legs fixed and comes to rest with an upward acceleration of 3 g. Force exerted by him on the ground during landing is

• A. W
• B. 2W
• C. 3W
• D. 4W

Answer 1

The correct option is D 4W

A parachuitist of weight $W$ strikes the ground with his legs fixed and comes to rest with an upward acceleration of $3g$

$Mg=W$

$N-W=3mg$

$N-W=3W$

$N=4W$
