Speed problem including the speed of sound

AI Thread Summary
To determine the speed of the bowling ball, the total time of 2.5 seconds includes both the time for the ball to reach the pins and the time for the sound to travel back. The distance to the pins is 16.5 meters, and the speed of sound is assumed to be 340 m/s. Using the formula t = d/Vb + d/Vs, where Vb is the speed of the ball and Vs is the speed of sound, the equation can be rearranged to solve for Vb. The calculated speed of the ball is approximately 6.6 m/s, but this does not account for the time taken for the sound to return. Therefore, the actual speed of the ball is higher than 6.6 m/s when considering the speed of sound.

Homework Statement


A bowling ball traveling at constant speed hits the pins at the end of a bowling lane 16.5m long. The bowler hears the sound of the ball hit the pins 2.5 seconds after the ball is released. What is the speed of the ball?


Homework Equations


Distance=16.5m
Time=2.5 s

The Attempt at a Solution


s=d/t =16.5/2.5 =6.6m/s

how does the speed of sound effect the overall speed of the ball?

Total time t = d/Vb + d/Vs. You have assume the velocity of sound = 340 m/s. t is given.Find Vb, the velocity of the ball
 
Thanks for the help =)

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
