I feel bad for wasting your time with this stupid question now. Lets just end it here, but I'll need confirmation on my attempt. My attempt: Potential Energy in the spring stays the same and exerts the same amount of energy on the block. However the work done on the block is different. Since...

This is a modified version of the problem statement due to the original being more confusing because this was given by a student teacher whose English isn't her first language. I think saying that the two blocks being fused together might have been a mistake and she meant one block. If you want...

No sketch. This is why I'm confused too. Basically the block is going down the ramp via a spring launching it. The block and ramp have friction between them. After the block is launched, it will have a displacement due to the work done by the spring and (I assume) gravitation potential energy...

Homework Statement A spring is used to launch a two 1kg blocks down a ramp from the top. One of the block is stack (fused) on top of the other. If the mass of the blocks were to change, i.e. double (making it 2kg blocks). does this change the displacement of this system? This system also has...

:nb) Sorry, argh, shouldn't get something so simple wrong! :nb) So I'm guessing T = Fnet Fnet(m1) = ma = 2*3 = 6N Fnet(m2) = ma = 3*3 = 9N T = kx Since Mass 2's forces are balanced (guessing here), I should use Fnet(m1). 6 = kx 6 = 130x x = 6/130 x = 0.046 metres (3dp) Cheers Chet :smile:

T = 15-T 2T = 15 T = 15/2 T = 7.5N

Mass 1: Fnet = ma 15 = 2a a = 15/2 a = 7.5m/s2 Mass 2: Fnet = ma 15 = 3a a = 15/3 a = 5m/s2

So what I drew is basically both blocks having a downward force of mg and an upward force of N of equal magnitude as mg. For Mass 1, I drew an arrow to the right as T (tension). For Mass 2, I drew an arrow to the right as F (15N pulling the mass to he right) and an arrow to the left as T...

Homework Statement | Mass 1: 2kg | -------- | Mass 2: 3kg | ----------> 15N 2 blocks are connected by a massless spring on a horizontal frictionless plane. The left block has a mass of 2kg and the right block has a mass of 3 kg. There is a force pulling Mass 2 to the right with a force of...
