Question

The $v-t$ curve shown above is a straight line parallel to time-axis. The displacement in the time interval $t =0$ and $t=T$ is equal to

• A. $\mu T$
• B. Area of the rectangle of height $\mu$ and base $T$
• C. Both (a) and (b)
• D. Slope of the curve

Answer 1

Answer: (C)

For the graph shown, area under the $v-t$ curve represents area of the rectangle of height $\mu$ and base $T$.
$\because$ Area under the $v -t$ curve
$=$ Displacement during $t=0$ and $t=T$
$=\mu \times T =\mu T $
