I have an basic kinematics problem I can't seem to grasp -- hopefully someone can shed some light on it for me?

**The acceleration, a, of an object is equal to a=s, where s is the**

distance from the start position. Sketch a graph representing velocity

against distance, s, for the object if, at t=0, the velocity v=u and s=0.

This is particularly frustrating, as it appeared in a very early tutorial and the rest of the course has been fine...

Another example of essentially the same problem is:

**The angular acceleration, α, of an object is given by α = 2ω, where ω is the angular velocity.**

Sketch a graph representing angular velocity against angle, θ, rotated from the start position for the object if, at t = 0, the angular velocity ω = ωo and θ = 0.

Thanks for any help!
