the values of m, k1 and k2 are given (k1 > k2 ). Initially, both springs are relaxed. Then the left block is slowly pulled down a distance x and released.

Find the acceleration of each block.

sorry about no latex in a hurry :)

F = ma

F = -Kx

ma = -kx

a = -kx/m

Since extension is occurring on the left hand side x is positive.

Since compression takes place on the right hand side x is negitive.

a = -k(+or-x)/m

I was in a bit of a hurry but I've tested with some values and it seems ok, but i'd love some help if this is wrong.
