Question

Determine the displacement of the object between 0 and 9 seconds

Answer 1

The displacement of the object can be calculated by calculating the area under the curve as,

`\begin{gathered} d=(1)/(2)(9-0)(6-(-12)) \\ =(1)/(2)(9)(18) \\ =81\text{ m} \end{gathered}`

Thus, the displacement of the object is 81 m.
