(a)[3]
Describe the motion of the bus between each of the bus stops. Choose the correct description from the list below. constant acceleration decreasing acceleration increasing acceleration moving backwards at constant speed moving forwards at constant speed stationary 1. between A and B 2. between B and C 3. between C and D
(b)[3]
Calculate the distance between A and D.
(c)[3]
On Fig. 1.1, sketch a suitable graph for this extra motion. Mark X when the bus begins to accelerate and mark Y for 30 seconds afterwards.
