A stone dropped from the top of a tower ...

A stone dropped from the top of a tower of height 300 m high splashes into the water of a pond near the base of the tower. When is the splash heard at the top givne that the speed of sound in air is `340 ms ^(-1) ? (g =9.8 ms ^(-2))`

Text Solution

Verified by Experts

The correct Answer is:
`8.707 s`
`h=(1)/(2)g t_(1)^(2)rArr t_(1)=sqrt((2h)/(g))and h=vt_(2),t_(2)=(h)/(v)=(300)/(340)`
`:. t=t_(!)+t_(2)=8.707 sec`
