A ball is thrown vertically upwards with a velocity of `20 ms^(-1) ` from the top of a multistorey building. The height of the point from where the ball is thrown is 25.0 m from the ground.
How high will the ball rise ?

Text Solution

Verified by Experts

Initial velocity ` V_(0) = 20 m//s` , height above ground ` h_(0) = 25 . 0 m, g = 10 m// s^(2)`
For a body thrown up vertically height of rise
` ( y - y_(0)) = ( u^(2))/( 2 g) = ( 20 xx 20)/( 2 xx 10) = 20 m `
