A ball is dropped from the top of a building .It takes 0.5 s to fall past the 3m length of a window some distance from the top of the building .If the velocity of the ball at the top and at the bottom of the window are `V_(T)` and `V_(B)` respectively then `V_(T)+V_(B)=?`

Text Solution

Verified by Experts

`S=((u+v)/2)t`
`3=((v_T+v_B)/2)0.5`
`V_T+V_B` =12 m/s
