AI Thread Summary
To calculate the change in height in a ballistic pendulum lab, the relevant equations involve energy conservation and projectile motion principles. The initial and final heights can be determined using the given variables, including bullet mass, block mass, and gravitational acceleration. The maximum height can be found by analyzing the vertical motion of the pendulum after the bullet embeds itself. It is essential to refer to the lab's provided write-up for specific formulas and guidance. Understanding these concepts will facilitate accurate calculations of height change and bullet velocity.

Calculate change in height?
I am working on a ballistic pendulum physics labs. I am trying to find the change in y(height) and bullet velocity.

I ran the lab and received the following results:
t (at max height (.780)
in y= -.984
final y= -789
m(bullet)=.001
m(block)=.05
g=9.81
x in= 1.452
x final=2.371

I have no idea how to calculate the height change.

thanks

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...
