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 'Struggling to make relation between elastic force and height'

Hello guys this is what I tried so far. I used the UTS to calculate the force it needs when the rope tears. My idea was to make a relationship/ function that would give me the force depending on height. Yeah i couldnt find a way to solve it. I also thought about how I could use hooks law (how it was given to me in my script) with the thought of instead of having two part of a rope id have one singular rope from the middle to the top where I could find the difference in height. But the...

TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...
