AI Thread Summary
To determine the speed of a bowling ball hitting pins at the end of a 16.5 m lane, the total time from release to hearing the sound of impact is 2.50 seconds. Given the speed of sound is 340 m/s, the time for sound to travel back to the bowler must be calculated. Subtracting the time for sound from the total time allows for the calculation of the ball's speed using the formula speed = distance/time. The resulting speed of the ball is 6.6 m/s at the moment it strikes the pins. This calculation provides the speed, but not the velocity, which requires directional information.

Hi guys,

I have one homework problem I can't figure out. :mad:
Pleace, can you help me? Please

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

Thanks

You are given the total time for the ball to travel the length of the ally and the sound to return. Use the speed of sound and the length of the ally to find the time required for the sound to travel back to the bowler. You now know the time for the ball to travel the distance. Use the fact that the ball travels at a constant velocity to complete the problem.
 
for reaching out for help! Let's break down the problem and see if we can figure it out together. We know the distance (16.5 m) and the time (2.50 s) it takes for the sound of the ball hitting the pins to reach the bowler. We also know the speed of sound (340 m/s).

To find the speed of the ball, we can use the formula speed = distance/time. In this case, the distance is the length of the bowling lane (16.5 m) and the time is the difference between when the ball was released and when the sound was heard (2.50 s).

So, the speed of the ball = 16.5 m/2.50 s = 6.6 m/s. This is the speed of the ball at the moment it hits the pins.

Keep in mind that this is just the speed, not the velocity. Velocity includes direction, so we would need more information to determine the velocity of the ball.

I hope this helps! Let me know if you have any other questions. Good luck with the rest of your homework!
 
I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...
Thread 'A cylinder connected to a hanging mass'
Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
