[Wait until the applet loads completely {you will see a message down in the status bar saying it is "running"} before pressing PLAY.]
A ball moves across the screen with an increasing velocity. [Note: it starts "off screen" to the left.]
What is the acceleration of the ball? (You should be able to calculate it from the "show velocity" mode, but could you also calculate it from the "show X" mode?)
Display Options : X coordinate not shown X coordinate shown V coordinate shown Animation with Ghosted object
The calculated acceleration should be 2 m/sec.
