2 blocks of masses m1 and m2 are joined by a light spring on a horizontal table. Obtain the relation of their accelerations a1 and a2 after they separate a bit and get released.
I tried to use the equations V(x)= .5k*x^2 (potential energy) and V = -∫Fdx
I set -∫Fdx = .5k*x^2, but didn't know if that was right or what to do after. Do I divide x^2 over to the dx and integrate, or change F to F=ma?
help!
