Momentum Problem


The mass on the left is 1.0 kg. The two masses are locked together with a spring trying to push them apart. When “play” is presses, the masses are released and travel in opposite directions. The spring exerts its force equally to the two masses. Measure the relative velocities of the two masses. Position is in meters and time is in seconds.


1. What is the value of the right-hand mass? Use the relative velocities.

2. What is the velocity of the center of mass of the two carts after the spring is released. Start
