Question

A bowling ball traveling with constant speed hits the pins at the end of a bowling lane 16.5m long. The bowler hears the sound of the ball hitting the pins 2.50s after the ball is released from his hands. What is the speed of the ball? The speed of the sound is 340 m/s.

Answer 1

The ball takes 15/V secs to reach the pin since T=D/V. so there for the Sound takes 15/340 secs to reach the bowler. The total time enlapsed then is 15/V + 15/340 = 2.10 So 15/V =2.1 -15/340
V = 7.296 m/s
