Homework Help: physics

Posted by Leticia on Monday, October 14, 2013 at 2:19pm.

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? (That is, when the two masses separate from each other after the collision is complete.)
