The objective of this video is to consider rectilinear motion with variable acceleration followed by a comprehensive workout on an exemplary problem. In the introductory video of rectilinear motion, it has been described that sometime there are needed to solve problem of rectilinear motion having variable acceleration where the previously used formulas are no longer effective to use to solve the problems. In such cases, if anyone of the displacement, velocity and acceleration is given as function of time, then it is necessary to work out on remaining parameters.

Moving on, the video presents an example of rectilinear motion with variable acceleration where it asks to calculate the displacement, velocity and acceleration after 6 seconds from start up based on the given function of displacement with respect to time. The video shows step by step how to do the calculations and later presents another example of finding out the time required to reach a particle velocity at constant value based on the given function of displacement with reference to time.
