Acceleration Final Speed

AI Thread Summary

To find the average acceleration of a baseball that accelerates over a distance of 3.5 meters from an initial speed of 0 m/s to a final speed of 41 m/s, the appropriate formula is derived from kinematics. The formula to use is $ a = \frac{(v_f^2 - v_i^2)}{2d} $, where $ v_f $ is the final speed, $ v_i $ is the initial speed, and $ d $ is the distance. Plugging in the values, the average acceleration can be calculated. The discussion emphasizes the importance of assuming constant acceleration for accurate results. Understanding the correct application of kinematic equations is crucial for solving such physics problems.

1. A pitcher uses 3.5m to accelerate a baseball before release. Find the average acceleration of a ball starting at zero m/s and traveling 41m/s at release

Thanks in advance. I'm lost with what I need to do.

Hi aprymek! Welcome to PF!

Assume a constant acceleration …

you know the initital and final speed, and the distance, so which formula should you use?

Thread 'Errors and significant figures'

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...

Thread 'Explain this asphalt sheen'

This problem is two parts. The first is to determine what effects are being provided by each of the elements - 1) the window panes; 2) the asphalt surface. My answer to that is The second part of the problem is exactly why you get this affect. And one more spoiler:
