On a frictionless horizontal surface, block A of mass 2.00 kg slides to the righ

Question

On a frictionless horizontal surface, block A of

mass 2.00 kg slides to the right at 15.0 m/s and

block B of mass 4.00 kg slides in the same direction

at 3.00 m/s. A massless spring of spring constant

k =1,120 N/m is attached on the back of block B.

The masses will have an interaction via the spring, and will move apart afterwards.

(a) Find the maximum compression distance, x, of the spring between them when block A

catches up with block B.

(b) Find the final velocity of block A after the collision.
