The time versus distance for two runs of a RipStik were recorded in the table below.
Plot the data using circles and squares for A and B respectively.
__________ __________ Calculate the velocity for RipStik run A.
__________ __________ Calculate the velocity for RipStik B from 0 to 2 seconds.
__________ __________ Calculate the velocity for RipStik B from 2 to 4 seconds.
__________ __________ Based on the above two calculations, by how much did the velocity increase for RipStik B?
__________ __________ Calculate the average acceleration of RipStik B over the four seconds from 0 to 4 seconds by dividing the change in velocity by four seconds.
__________ __________ The curve on the graph is the acceleration of RipStik. Using the point D (5 seconds, 800 cm) and the equation d = ½at², calculate the acceleration of the RipStik.
