Sound (10)A person is standing at the sea shore. An observer on the ship which is anchored in between a vertical cliff and the person on the shore fires a gun. The person on the shore hears two sounds, 2 seconds and 3 seconds after seeing the smoke of the fired gun. If the speed of sound in the air is 320 ms-1 then calculate:
- the distance between the observer on the ship and the person on the shore.
- the distance between the cliff and the observer on the ship.
Answer
(i) d = v × t = 320 × 2
d = 640 m
(ii) d = (v×t)/2= (320×1)/2
d = 160 m
