A bowling ball traveling with constant speed hits the pins at the end of a bowling lane 17.5 m long The bowler hears the sound of the ball hitting the pins 2.60 s after the ball is released from his?

Answer 1

... What is the speed of the ball?

Distance = 17.5 m Time = 2.6 sec Speed (of sound) = 340 m/sec

Speed (of ball) = ?

Typically Speed = Distance/time (which means 17.5/2.6. But here we also have to calculate the speed of the sound of the ball traveling when the ball hits the pins till it reaches the ears of the bowler)

Time (of sound) = Distance/Speed (of sound) = 17.5/340 = 0.0515 sec

Time (of ball) = 2.6 - 0.0515 =2.5485 sec

Speed (of ball) = Distance/Time (of ball) = 17.5/2.5484 = 6.87 m/sec
