a bowling lane is 16.5m long. A young bowler throws a strike and hears the pins striking the floor 4.1 seconds after releasing the ball. How fast was the ball traveling? (The speed of sound in air is 343 m/s)
time=time for ball to go to pins+timeforsound.
time for sound=16.5/vsound
solve for time for ball to go to pins, thekn solve for how fast.
