Book Free DemoA boy is moving on a straight road against a frictional force of \(5\ N\). After travelling a distance of \(1.5\ km\) he forgot the correct path at a round about (Shown in fig.) of radius \(100\ m\). However, he moves on the circular path for one and half cycle and then he moves forward upto \(2.0\ km\). Calculate the work done by him.
