The diagram illustrates the velocity-time graph of a body. Calculate the distance covered by the body during the motion
A.
15m
B.
84m
C.
72m
D.
48m
Correct answer is C
Distance covered = Area under the graph
D = area of square + area of trapezium
D = L x L + 1/2(a+b)h
D = 4 x 4 + 1/2( 4+ 10)8
D = 16 + 1/2 x 14 x 8
D = 16 + 56
D = 72m.
