## Homework Statement

A bowling ball traveling with a 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 pins 2.5 s after ball is released from his hands. What is the speed of ball, assuming speed of sound is 340 m/s?

## Homework Equations

the kinematic equations

x=x0+v0t+.5at^2

v=v0+at

vf^2=v0^2+2ax

## The Attempt at a Solution

Well, I thought that somehow I could use the time it takes for the sound wave to travel up and down the bowling lane, which is (33 m)/(340 m/s)= about .097 s. See I can picture the problem in my head, but I don't know how to get t for the ball in order to find the speed.
