Ahunter shoots a bullet horizontally at a rock cliff wall that is 170 m away. she hears the sound of the bullet hitting the rock 0.95 seconds later. knowing that the speed of sound was 340 m/s, what was the speed of the bullet?

377.78 m/s

Explanation:

Let the speed of bullet is v.

Time taken by the sound is t' and time taken by the bullet is t.

Speed of sound = 340 m/s

Distance = 170 m

Time taken by the sound, t' = distance / speed of sound = 170 / 340 = 0.5 sec

time taken by the bullet, t = 0.95 - 0.5 = 0.45 sec

Speed of bullet = distance / time taken by bullet

Speed of bullet = 170 / 0.45 = 377.78 m/s
