two linked are attached to each other with a spring. If the second body is placed on a fixed support, the length of the spring is 5 cm. If we fix the first body as in the picture, the length of the spring becomes 15cm. Determine the length of the spring in the non-deformed state.
m1 = 1 kg;
m2 = 4kg;
l1 = 5cm;
l2 = 15cm;
This time i have really no idea. The m1 pushes the spring with a force of 10N and m2 should like respond with another force? Quite don't get it.

Any help would be greatly appreciated.
