... 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
