## Homework Statement

The students set up a cart with a spring attached to the force probe.They weigh the cart assembly and find that its mass is 734.0 g. They launch the cart towards the target and collect the following force-vs.-time data.

The students discover that Data Studio has an “area under the curve” feature. They use this and find the total area under the curve to be 0.4209 N·s.

1) Assuming a perfectly

**inelastic collision**, what is your best estimate of the speed of the cart before the collision?

2) Assuming a perfectly

**inelastic collision**, what is your best estimate of the speed of the cart after the collision?

*what would you do for an

**elastic collision**?

## Homework Equations

elastic

1/2m1v1^2 + 1/2m2v2^2= 1/2m1v1'^2 +1/2m2v2'^2

## The Attempt at a Solution

very confused even on how to start this question...

how would we calculate without the mass of the other object?

cannot find the equations that go from a given impulse (force and time) to velocity. help???
