Question

A stone is dropped from tap of tower 325m high into pond of water at the base of tower when the splash hard at tap Given g=10ms‐² and speed of sound =340ms‐¹

Answer 1

Answer:

Explanation:

Height of the tower H=325m

Velocity of sound V=340m/s

Acceleration due to gravity g=10m/s^2

Initial velocity of stone U=0

S=ut+1/2gt^2

325=1/2*10*t1^2

t1=8.06 seconds

Time taken by sound to reach the top from base of tower t2=325/340=0.95 seconds

Total time=t1+t2=8.06+0.95=9.01 seconds
