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 2.51s after the ball is released from his hands. What is the speed of the ball? The speed of sound is 340 m/s

Answer 1

time=time for ball to roll+timefor sound to come back.

2.51=speedball(2.51-tsound)+tsound

but tsound=16.5/340

solve for speedof ball

Answer 2

Speed of ball is distance traveled divided by (time of hearing minus time the sound travels).

16.5/(2.51-16.5/340) m/s = 6.70 m/s
