Mansi Garg and Jitendra Kumar Solutions for Chapter: Motion in One Dimension, Exercise 4: CHAPTER EXERCISE

A circular track has a circumference of $s \mathrm{m}$ with AB as one of its diameter. A scooterist moves from A to B along a circular path with a uniform speed of $v$ $\mathrm{m}/\mathrm{s}$. Find the expression for time taken by the scooterist in moving from A to B?

The graph given below is the distance-time graph of an object. Find expression for the speed of the object during the first $t_1$ second of its stationary position.
