A ball is thrown vertically upwards with a velocity of `20ms^-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=20m//s`,
Height above ground `h_0=2.50m,`
`g=10m//s^2`
a) For a body thrown up vertically height of rise
`(y-y_0)=u^2/(2g)=(20times20)/(2times10)=20m`
