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=(20-20)/(1-0) \\ v=(0)/(1) \\ v=0ms^(-1) \end{gathered}`

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