A person pushes a box on a rough horizontal plateform surface.He applies a force of 200 N over a distance of 15 m. Therefore, he gets progressively tired and his applied force reduces linearly with distance to 100 N. The total distance through which the box has been moved is 30 m. What is the work done by the person during the total movement of the box?

A woman pushes a trunk on a railway platform which has a rough surface. She applies a force of 100 N over a distance of 10m. Thereafter, she gets progressively tired and her applied force reduces linearly with distance to 50 N. The total distance through which the trunk has been moved is 20m. Plot the force applied by the woman and the frictional force, which is 50 N versus displacement. Calculate the work done by the two forces over 20 m.

A woman pushes a trunk on a railway platform which has a rough surface. She applies a force of 100N over a distance of 10m. Thereafter, she gets progressively tired and her applied force reduces linearly with distance to 50N. The total distance through which trunk has been moved is 20m. Plot the force applied by the woman and the frictional force, which is 50N against the distance. Calculat the work done by the two forces over 20m.

A gardener pushes a lawn roller on a rough surface. He applies a force of 150 N over a distance of 5 m. After he gets tired and his applied force reduces linerly with distance to 75 N. The total distance moved is 10 m. Plot the force applied by the gardencer and the frictional force, which is 75 N versus displacement. Calculate the work done by t he two forces over 10 m.
