Question

A boy is moving on a straight road against a frictional force of $5 N$ . After travelling a distance of $1.5 k m$ he forgot the correct path at a round circle of radius $100 m$ . However, he moves on the circular path for one and half cycle and then he moves forward up to $2.0$ km. Calculate the work done by him.
