A block of mass m1 = 2.4 kg initially moving to the right with a speed of 3.3 m/s on a frictionless, horizontal track collides with a spring attached to a second block of mass m2 = 4.1 kg initially moving to the left with a speed of
1.5
m/s as shown in figure (a). The spring constant is 514 N/m.
What will be the individual velocities of the two masses (v1 and v2) after the spring extended fully again?
