A body of mass m thrown horizontally with velocity v, from the fop of tower of height h, touches the level of ground at a distance of 250 m from the foot of the tower. A body of mass 2 m, thrown horizontally with velocity v/2, from top of the tower or'height 4 h will touch the level ground at a distance in meter from the foot of the tower is

Options

A. 150m
B. 200
C. 250
D. 2500 m

Explanation

`V_(bg)=3hati+4hatj`
`V_(wg)=-3hati-4hatj`
`V_bw=V_bg+V_wg`
`V=(3hati+4hatj)-(-3hati-4hatj)`
`:.V=6hati+8hatj`
