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.
To find out how fast the ball was traveling, we need to calculate the distance it traveled.
We know that the length of the bowling lane is 16.5m. Therefore, the ball traveled this distance in 4.1 seconds.
To calculate the ball's speed, we divide the distance by the time it took:
Speed = Distance / Time
Speed = 16.5m / 4.1s ≈ 4.0244 m/s
So, the ball was traveling at approximately 4.02 m/s.
Please note that this calculation assumes that the ball traveled the entire length of the lane and the sound of the pins striking the floor reached the bowler immediately after the ball's release. In reality, there might be some delay between the ball reaching the pins and the sound traveling back to the bowler.
