Q.
A body is moving in a straight line a shown in velocity-time graph. The displacement and distance travelled by in 8s are respectively
A) 12 m, 20 m
B) 20m, 12 m
C) 12 m, 12 m
D) 20 m, 20 m
Explanation
(a) Displacement $= (2 \times 4 - 2 \times 2 + 2 \times 4) =$12m
$= 2 \times 4 + 2 \times 2 + 2 \times 4$=20m
