The first four questions are matching. Use the letters A, B, C, and D at the end of the lines on the xy scattergraph.
_____ Ball not moving: stationary.
_____ Ball slowing down.
_____ Ball moving at a constant non-zero speed.
_____ Ball speeding up.
___________________ Determine the speed of ball D.
___________________ Determine the speed of ball B.
___________________ Determine the speed of ball A between 7 and 8 seconds.

The following two graphs plot the constant speed linear motion of the RipStik on 17 January and the accelerated motion of the RipStik on 24 January. Label the graphs indicating which is graph linear and which is accelerated.
Each of the three graphs plots time versus velocity for a RipStik. The slope of the lines is the acceleration. The graphs are marked A, B, and C.
_____ Which graph is a constant velocity with zero acceleration?
_____ Which graph is an increasing velocity with a constant acceleration?
_____ Which graph is an increasing velocity with a increasing acceleration?
___________ How many numbers did Descartes use to specify points in space?
___________________ The equation on a graph of a moving RipStik with time in seconds on the x-axis and distance in meters on the y-axis is y = 1.43x. What is the speed of the RipStik?
