Answer» <P>Answer: Let the speed of the man in upward direction be V. Applying conservation of linear momentum of man and STONE SYSTEM : P f =P i M man V−M stone V stone =0 Or 50V−0.5×2=0 ⟹ V=0.02 m/s Time taken by stone to reach the GROUND t= 2 m/s 10 m =5 s Distance covered by man in 5 s, d=Vt=0.02×5=0.1 m (in upward direction) Thus distance of man above the floor h=10+0.1=10.1 m..

<P>Answer:

Let the speed of the man in upward direction be V.

Applying conservation of linear momentum of man and STONE SYSTEM : P

man

V−M

stone

Or 50V−0.5×2=0

⟹ V=0.02 m/s

Time taken by stone to reach the GROUND t=

2 m/s

10 m

=5 s

Distance covered by man in 5 s, d=Vt=0.02×5=0.1 m (in upward direction)

Thus distance of man above the floor h=10+0.1=10.1 m..
