Question

The figure below shows the position of a ball at t = 0, t = 1s, t = 2s, t = 3 s and t = 4s.

Which of the following position-time graph is possibly correct for the situation shown above?

• A.
• B.
• C.
• D.

Answer 1

The correct option is A

The figure represents the relation between the change in position (x) with respect to time(t).

Here, x is decreasing with increase in time. So, the value for x will be maximum when t = 0, and gradually, the value of x decreases with increase in time.

Also, the change in position decreases with time, therefore we can say the graph will be a curve and not a straight line.

All these observations lead to the curve given below.
