Question

If the velocity of a particle and corresponding time be plotted along $y$ and $x$ axes respectively, then which of the following statements is correct?

• A. the curve may lie in fourth quadrant
• B. the curve may lie in second quadrant
• C. the curve may exhibit peaks corresponding to maxima
• D. the curve may drop as time passes

Answer 1

Answer: (A), (C), (D)

the curve may exhibit peaks corresponding to maxima
the curve may lie in fourth quadrant
the curve may drop as time passes

The curve can take any shape according to the nature of the function (i.e. It may increase or decrease).
The cure can never lie in $2nd$ and $3rd$ Quadrant because time can never be negative. It has to lie either in $1st$ or $4th$ Quadrant.
