Draw a simple graph that shows constant acceleration. Label the x and y axis.
It should be a velocity vs time graph, with a straight diagonal line (showing constant acceleration). //OR//
An acceleration vs time graph, with a flat horizontal line.

Dominic Roth is in a roller coaster car, which rapidly picks up speed as it rolls down a slope. As it starts down the slope, its speed is 4 m/s. But 3 seconds later, at the bottom of the slope, his speed is 22 m/s. What is its average acceleration?
6 m/s2 (you must include units for the points)
Acceleration = Change in Velocity / Time
