MCQ

A particle, initially at rest on a frictionless horizontal surface, is acted upon by a horizontal force which is constant in size and direction. A graph is plotted between the work done $(W)$ on the particle, against the speed of the particle, $(v)$. If there are no other horizontal forces acting on the particle the graph would look like

A
B
C
✓

✓

Answer

Correct option: D.

(d) Work done = change in kinetic energy$W=\frac{1}{2} m v^2 \therefore W \propto v^2$graph will be parabolic in nature
