Question

A ball is dropped into a pond from a height of 44.1m. The splash of sound is heard 3.13 second after the ball is dropped. Determine the velocity of sound in air.​

Answer 1

Answer:

velocity of sound is nearly equal to 339m/s.

Explanation:

The time required to reach the pond from the top is

S=ut+½at²

44.1=0.t+½ x 9.8 x t²

44.1= 4.9 x t²

t=3sec

then the time of heard the splash of sound is 3.13s

the time of heard the sound from the pond is(3.13-3)= 0.13s

velocity of sound =44.1/0.13= 339m/s
