Question

Two blocks are connected by
unstretched spring and mass
m is given a velocity vo = 24
m/s towards 5 m as shown.
What is the maximum velocity of 5 m?​

Answer 1

Answer:

At maximum elongation the two blocks are moving with same speed, thus, the conservation of linear momentum and energy gives us:
