A stone is dropped from the top of a tower and it hits the ground at `t = 3.5s`. If the velocity of sound in air is `300 ms^(-1)`, find the time taken to hear the sound by a person on the top of the tower, from the instant the body is dropped `(g = 10 ms^(-2))`

Text Solution

Verified by Experts

(i) `S = (1)/(2) "gt"^(2), V = (d)/(t)`
(ii) `3.75 s`
