Question

A stone is dropped from the top of a tower 200 m high in a pool of
water at the base of the tower When is the splash heard at the
top?
(Given g = 10 m/s^2 and speed of the sound is 340 m/s)

Time taken to hear splash at top=(Time taken by stone to
reach pool)+(time taken by this sound produced to be heard at
top)

~~Time taken by stone to reach pool
s=ut+1/2at2
here s=200m u=0m/s(as when itwas dropped,it was at rest)
a=g=10m/s2
On substituting values,
t=6 32s

~~time taken by this sound produced to be heard at top
s=d/t
here, s=340m/s d=200m
t=d/s=200/340=0 588s

Total Time=6 32+0 588=6 9s=Time taken to hear splash at
top
