Graphically, derive the equation of motion '100" "km//h' at and hence use it to find the acceleration of a car whose velocity increases from '50" "m//s' to 'v=u 2' in a time of 4hours.

We might know that the greater the acceleration of, say, a car moving away from a stop sign, the greater the displacement in a given time. But we have not developed a specific equation that relates acceleration and displacement. In this section, we develop some convenient equations for kinematic relationships, starting from the definitions of displacement, velocity, and acceleration already covered.
