Vedclass · Answer

(A) The speed of sound $V = 310 \, m s^{-1}$.The time taken for the echo to be heard is $t = 1.5 \, s$.Since the sound travels to the cliff and back to the person,the total distance covered is $2d$,where $d$ is the distance of the person from the cliff.The formula for speed is $V = \frac{2d}{t}$.Rearranging for distance: $2d = V 	imes t$.Substituting the values: $2d = 310 	imes 1.5 = 465 \, m$.Therefore,the distance $d = \frac{465}{2} = 232.5 \, m$.

The speed of sound is $310 \, m s^{-1}$. $A$ person fires a gun and the echo is heard after $1.5 \, s$. Calculate the distance of the person from the cliff from which the echo takes place. (in $, m$)
