Expert Solution
Step 1: Given

Mechanical Engineering homework question answer, step 1, image 1

The mass of block A is m subscript a equals 40 space k g.

The mass of block B is m subscript b equals 60 space k g.

The stiffness of spring is k equals 180 space N divided by m.

The initial stretch in spring is x subscript i equals 2 space m.

The final stretch is x subscript f equals 0

The initial velocity of A and B is zero.
