Question

find velcoity over the time interval from 0 to 1 second

Answer 1

From graph:

* The final value of position at time 1 second is 20 m.

* The initial value of position at time 0 second is 20 m.

Solution:

The velocity in terms of the position is,

$v=\frac{change\text{ in position}}{time\text{ interval}}$

For the time interval 0 to 1 second,

$\begin{gathered} v=\frac{20-20}{1-0} \\ v=\frac{0}{1} \\ v=0ms^{-1} \end{gathered}$

Thus, the velocity over the time interval from 0 to 1 second is zero meter per second
