Homework Statement
A 2kg block & 3kg block (left & right, respectively) are on a horizontal frictionless surface connected by a spring with K=140 N/m. A 15N force is applied to the 3kg block towards the right. How much does the spring stretch from its equilibrium length?
Homework Equations
F=-kx
others, maybe?
The Attempt at a Solution
I simply did force over constant, which is 15/140=0.107m. Is it this simple, or do you use the masses in some way?
Thank you!
