In a running race between 4 people, the 1st person did not start running as soon as the whistle was blown. He started running after a few seconds. The x-intercept of the v-t graph of the 1st person is ___.
- > 0
- < 0
- = 0
- Any of the above
The correct answer is: > 0
The x intercept will be positive as the runner didnt start at time t = 0.

In a mathematical problem, Samuel was provided with the values of s, u, and a and the value of t was asked to be calculated. Samuel substituted those values into the second equation of motion and got a quadratic equation in t as a result. He thought of plotting a graph taking t in the x-axis. How will the graph look like?
