## Homework Statement

A toy car is held at rest against a compressed spring, as shown in the figure. When released, the car slides across the room. Let x=0 be the initial position of the car. Assume that friction is negligible.

Sketch a graph of the car's kinetic energy from the moment it is released until it passes the equilibrium position of the spring. Your graph should be consistent with the given plots of total energy (gray line in graphing window) and potential energy (gray parabola in graphing window).

Part A and B asked for total Energy and gravitational PE. This is shown in attached file. The problem is with plotting KE. I can't tell if I got it wrong because my graph is sloppy or if I actually have the shape completely wrong. The line that is marked wrong is the red line, which is supposed to be KE

thanks for any help

## Homework Equations

As PE decreases KE will increase, so that total E always constant. This is what I thought I plotted (?) thanks
