(a(i))[2]
For Fig. 1.1, link each letter, R, S and T, to the motion at that point. Draw one line from every letter to the right description. One has already been completed for you. Letter on the graph: R, S, T. Descriptions of motion: at rest; moving with constant speed; decelerating (negative acceleration); accelerating (positive acceleration).
(a(ii))[1]
Determine the speed of the car when time = 4.0 s.
(a(iii))[3]
Determine the distance moved by the car between time = 16.0 s and time = 20.0 s.
(b)[1]
Define the term velocity.
