Speed and velocity problem

  1. Sep 19, 2004 #1
    Hi guys,

    I have one homework problem I can't figure out. :mad:
    Pleace, can you help me? Please

    A bowling ball travelling 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 the sound is 340 m/s.

    Thanks

    You are given the total time for the ball to travel the length of the ally and the sound to return. Use the speed of sound and the length of the ally to find the time required for the sound to travel back to the bowler. You now know the time for the ball to travel the distance. Use the fact that the ball travels at a constant velocity to complete the problem.
