Question

Figure shows the displacement-time graph for the motion of two boys A and B along a straight road in the same direction. Which of the two has greater velocity?

• A. B
• B. A
• C. Both have same velocity
• D. None of the above

Answer 1

The correct option is A B

From a graph of displacement vs time, the slope gives the rate of change of displacement or velocity

From the given graph the velocity of $A$ is $\frac{20}{4}=5km/hr$

$\&$

Velocity of $B$ is $\frac{20}{2}=10km/hr$
