Question

hey beautiful people answer my question...

Answer 1

then the velocity will be 3 times more so aa to cover up such heights 3 times than its v 3


let a body with velocity v covers height h
than
when we takes height 3h than we have to give the velocity= v/1*3
therefore the velocity we require will be 3v


Hope it helps

Answer 2

so velocity is √3 of initial velocity
