Yeah I found the forces acting downwards but I think they are irrelevant because all the acceleration for the system would be in the sideways direction. I found that the acceleration of the 3kg (larger) mass is 15/3= 5ms/^2, but I'm not sure if this is correct because wouldn't the spring be...

Hello I am trying to find the acceleration of a system that has 2 masses, m1 and m2 connected via a spring with a spring constant of k with a force of F applied to the larger mass in the direction that stretches the spring.

What do they mean?

So, the 180 and 100 resistors are in parallel. So Rt = 1/((1/180)+(1/100)) + 120 = 184 ohms? Is that right because I thought for a pair of components to be in parallel, both sides had to be connected to the same node.

Sorry I still can't see it

Aren't they all in series though? or am i missing something

Hi thanks, I thought you were supposed to take out all components except resistors in the circuit, current sources by open circuit and voltage sources through short circuit. Then just add up the total resistance of all the resistors, but that method does not seem to work on this problem, as none...

Homework Statement Homework Equations V=IR The Attempt at a Solution [/B] I found that the current around the circuit was 5mA using kirchhoffs law ( i think) If this is true then the T.E.V should be the voltage across the 120ohm resistor which is .6V (120*5e-3). Now I'm stuck and not sure...
