Ballistic Pendulum Experiment: Determining Muzzle Velocity and Projected Height

AI Thread Summary
The discussion focuses on calculating the muzzle velocity of a ball bearing in a ballistic pendulum experiment, with a determined value of 1.247 m/s. The second part of the problem involves predicting the maximum height the bearing would reach when fired vertically, requiring the use of kinematic equations or conservation of energy principles. The user expresses uncertainty about how to approach this projectile motion problem and seeks guidance. The conversation highlights the connection between the initial velocity and the expected height in projectile motion scenarios. The discussion concludes with the user feeling more confident about solving the height calculation.

Calculate the most reasonable muzzle velocity of the ball bearing given:

Mass of Bearing = .033kg
Mass of the Combination = .064kg
Length of Pendulum = .235m
Theta = 24 degrees

I was able to solve that and get Vmuzzle = 1.247 m/s^2

The second part of the question is what I'm having trouble with.

If we were to devise an experiment to check that the above muzzle velocity is correct by firing the bearing straight upwards, what height would you expect the bearing to reach (most reasonable)?

I'm pretty sure I can figure this out once I get a starting point. We covered this section in lab before lecture and I wasn't able to find a similar example looking ahead in the book to base a solution on.

Thanks!

The second part is a projectile motion problem. What's the initial velocity? The acceleration? Use kinematics. (You can also use conservation of energy, if you like.
 
Got it! Thanks Doc!
 

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...
