Question

The velocity-time graph of a body is shown in figure. The slope of the line is ' $m$ '. The distance travels by body in time T s :-

• A. $\frac{m v_{0}^{2}}{2 T}$
• B. $\frac{ v _{0}^{2}}{2 T }$
• C. $2 mv _{0}^{2}$
• D. $\frac{ v _{0}^{2}}{2 m }$

Answer 1

Answer: (D)

The distance, $s=\frac{v_{0} T}{2}$
Also, $m =\frac{ v _{0}}{ T },$
$\therefore T =\frac{ v _{0}}{ m }$.
Now $s =\frac{ v _{0}^{2}}{2 m }$
