Question

Please help me with this, it's a Kinematics Equation 2 problem!

Answer 1

The distance covered by the object is given as,

`d=ut+(1)/(2)at^2`

Plug in the known values,

`\begin{gathered} d=(0\text{ m/s)(9 s)+}(1)/(2)(2m/s^2)(9s)^2 \\ =0\text{ m+}81\text{ m} \\ =81\text{ m} \end{gathered}`

Thus, the distance covered by the object is 81 m.
