Spring problem - conservation of energy?

AI Thread Summary
The discussion focuses on a physics problem involving a spring gun that launches a 15.0g ball with a spring constant of 600 N/m, compressed by 5.00 cm. Participants emphasize the importance of energy conservation principles to solve for the ball's velocity upon leaving the gun and its maximum height when shot vertically. The potential energy stored in the spring must be calculated first to determine the kinetic energy of the ball. The conversation confirms that understanding potential energy is crucial before proceeding to specific calculations. Overall, the discussion highlights the application of energy conservation in solving mechanical problems.

Homework Statement


A 15.0g ball is to be shot from a spring gun whose spring has a constant force of 600 N/m. The spring will be compressed 5.00 cm when in use. How fast will the ball be moving as it leaves? How high will it go if the gun is pointed vertically?



Homework Equations


I'm not quite sure which equations to use! This is what I need help with.

You're on the right track by bringing up energy conservation.
 
do i find the potential energy of the system first, before trying to find these specific answers?
 
That's right
 

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...
