Some problems here ( Im running out of time )

- the object is affected by force which is accelerating it. If it affects object by time $\displaystyle t$ the object will move by distance of $\displaystyle s = 2t^2$ What is the average speed between 2 and 3 seconds?

- For function $\displaystyle y = f(x)$ is $\displaystyle f(3) = 2$ and $\displaystyle f'(3) = -1$ what is it?

I will post other problems here if I got problems. I need to be done with them in 3 days so I will do the ones I can and give others to you. With this cooperation I can accomplish the mission.
