Question

Below is a velocity-time graph of a body travelling along a straight line. Calculate the displacement covered by the body and acceleration of the body at t = 6 s.​

• A. Displacement: 75 m, Acceleration: 5 m/$s^2$
• B. Displacement: 75 m, Acceleration: -5 m/$s^2$
• C. Displacement: 55 m, Acceleration: 5 m/$s^2$
• D. Displacement: 55 m, Acceleration: -5 m/$s^2$

Answer 1

The correct option is D Displacement: 55 m, Acceleration: -5 m/$s^2$

D) Displacement: 55 m, Acceleration: -5 m/$s^2$.
Area under the curve in velocity time graph gives the displacement covered by the body.​
Slope of the curve of velocity-time graph at a particular instant of time gives acceleration of that body.​ ​ ​
