Question

The velocity-time graph of a body is shown in figure. The displacement covered by the body in 8 s is

• A. 9 m
• B. 12 m
• C. 10 m
• D. 28 m

Answer 1

Answer: (C)

Displacement in 8 s = Algebraic sum of the area under velocity-time graph
$=2\times 2+\frac{1}{2}\times 1\times 4+1\times 2+\frac{1}{2}\times 1\times 6-\frac{1}{2}\times 16-6\times 1+2\times 4$
$=4+2+2+3-3-6+8=10m,$
