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

Respuesta :

total time = ball travel time + sound travel time  

2.40 = Tball + 18.0 m / (340 m/s)  

Tball = 2.35 s  

V = d/t = 18.0 / 2.35 = 7.67 m/s
