a. (i) The velocity of a scooter is noted every second as shown:
Time (s): 0, 1, 2, 3, 4
Velocity (m/s): 0, 3, 7, 12, 18
Calculate the acceleration during each 1 s interval.
b. (ii) On the basis of your calculations, classify the motion as having uniform or non-uniform acceleration and state one supporting point.
