Question

The speed-time graph for a car is shown in figure below. Which part of the graph represents uniform motion of the car?

• A. From $t=0$ to $2s$
• B. From $t=6$ to $8s$
• C. From $t=4$ to $6s$
• D. Can not be detemeined

Answer 1

The correct option is B From $t=6$ to $8s$

During uniform motion, speed of the body is constant and the speed-time graph is parallel to the time axis. Hence, after $t=6s$, the motion of the car is uniform.
