Solution

The correct option is B 50 J
According to work energy theorem we know that,
Change in kinetic energy = Net work done.

We also know that net work done is
= Area under FS curve
=Area of tringle OAB Area of tringle BDC

=12×20×10(12×10×10)
=50 J

Hence the change in kinetic energy
=50 J

Option B is the correct answer
