An object is thrown between two tall buildings `180 m` from each other. The object thrown horizontally from a window `55 m` above the ground from one buiding strikes a window `10 m` above the ground in another building. Find out the speed of projection.
.

Text Solution

Verified by Experts

`t = sqrt((2 h)/(g)) = sqrt((2 xx 45)/(10))`
`t = 3 s`
`R = u T`
`(180)/(3) = u rArr u = 60 m s^-1`.
