Solution

The correct option is A $10$ J
$W = \int F d x$
Work done = area under curve and displacement axis
$W = 1 \times 10 - 1 \times 10 + 1 \times 10 = 10 J$

A force $F = 0.5 x + 10$ acts on a particle in the x direction. Here $F$ is in newton and $x$ is in metre. Calculate the work done by the force during the displacement of the particle from $x = 0$ to $x = 2$ metre.

The graph between the resistive force F acting on a body and the distance covered by the body is shown in the figure. The mass of the body is 25 kg and initial velocity is 2 m/s. When the distance covered by the body is 5m, its kinetic energy would be
