Physics

A block of mass m1 = 2.9 kg initially moving to the right with aspeed of 4.3 m/s on a frictionless, horizontal track collides witha spring attached to a second block of mass m2 = 5 kg initiallymoving to the left with a speed of 2.8 m/s as shown in figure (a).The spring constant is 572 N/m.
What if m1 is initially moving at 2.2 m/s while m2 is initiallyat rest?
(a) Find the maximum spring compression in this case. x = m
(b) What will be the individual velocities of the two masses(v₁ and v₂) after thespring extended fully again? (That is, when the two masses separatefrom each other after the collision is complete.)
v₁ = m/s to theleft
v₂ = m/s to theright
