The first part of the velocity graph says that the slope of this position graph has to increase. This means that it would be a parabola. Or, if you like you can use the following kinematic equation.

The velocity at a particular instant is equal to the slope of the tangent drawn on position-time graph at that instant. 3.Average acceleration is the change in velocity divided by the time ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...
