Detailed Solution

Given,

$A t t = 0 s v_{1} = 10 m / s a t t = 10 s v_{2} = - 20 m / s$

We know that by the work-energy theorem,

Work done by all forces= changes in kinetic energy.

$work done, W = \frac{1}{2} m ({v_{2}}^{2} - {v_{1}}^{2}) = \frac{1}{2} \times 2 (400 - 100) = 300 J$

Hence the correct answer is 300J.
