Question
Before the experiment a student makes the following prediction.
"Since the carts are each attached to identical springs, which are compressed the same distance, the lighter cart will end up with a larger
velocity."

In a physics lab student have two different setups. Each setup has a frictionless cart connect to an identical massless spring. For each trial
the springs are compressed against a force sensor mounted to the track. Each spring is compressed from the equilibrium position x, to the
compresses position x. When the released cart returns to position x, the spring is no longer in contact with the force sensor. The force
sensor is set to record force and time information.
