    Height Velocity
AI Thread Summary
The discussion revolves around calculating the velocity and height of an arrow using given parameters such as spring constant, mass, and gravitational acceleration. The participant successfully determined the height and shared a shortcut for calculating velocity, which is the square root of twice the product of gravitational acceleration and height. Using this formula, they calculated the velocity to be approximately 65.3 m/s. The focus is on verifying the calculations and ensuring the methodology is correct before submission. The conversation emphasizes the importance of understanding the physics behind projectile motion.

would like to see if this looks rite before bed...due tomorrow
 
This is great because I was just having trouble calculating velocity tonight and finally figured it out.

You've got the height right and a short cut I discovered to finding velocity is
that velocity equals the square root of 2xgxh

v=\sqrt{}2gh so v=\sqrt{}2x9.8x217.55

v=65.3m/s
 

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'

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...
