Question

Figure represents graphically the velocity of a car moving along a straight road over a period of 100 hours.

Calculate the acceleration along AB and the retardation along BC.

Diagram
Short Note

Solution

Acceleration along AB= (100 - 100)/(40 -20) = 0 ms-2
Retardation along CD= (100 - 50)/ (100 - 60) = 50/40 = 1.25 ms-2
