Question

For the given velocity-time graph of a body under motion, find the displacement of the body.​

• A. 160 m
• B. 180 m
• C. 150 m
• D. 260 m

Answer 1

The correct option is B 180 m

The area under the velocity-time graph gives the displacement. Area under the graph = Area (0 s - 5 s) + Area (5 s - 13 s)​

= (20 x 5) m + $\frac{1}{2}$(20 x 8) m​

= (100 + 80) m = 180 m​
