A bowling ball travelling with a constant velocity hits the pins at the end of a bowling lane 19.80m long. The bowler hears the sound of the ball hitting the pins 4.8s after the ball is released from his hands. What is the velocity of the ball? speed of sound is 343 m/s

Answer 1

time elapsed=timeforballTraveling+timeforSound
where time for ballTraveling= 19.8/Vs
and Time for sound=19.8/343
solve for Vs

Answer 2

d = Vs*T = 19.8
343T = 19.8
T = 0.058 s.

d = Vb*T
19.8 = Vb(4.8-0.058)
Vb =
