Question

The figure shows four graphs of displacement ($x$) versus time ($t$), the graph that shows a constant, positive, and non-zero velocity is:

• A. $\left(a\right)$
• B. $\left(b\right)$
• C. $\left(c\right)$
• D. $\left(d\right)$

Answer 1

Answer: (A)

$\left(a\right)$

For constant velocity, the slope is constant, & for velocity to be non zero it lids to be at an angle & for it to be positive it should make an acute angle with the horizontal, hence option A is suitable.
