Diagram shows a velocity-time graph for a car starting from rest. The graph has three sections \( A B, B C D C D \).
(a) Compare the distance travelled in section \( A B \) and \( B C \).
-(b) In which scction car has zero acceleration and why?
(c) What is the magnitude of retardation between time \( 2 t \) to \( 3 r \) ?
- (d) Calculate tomal distance travelled in time b to \( 3 \mathrm{t} \).
