Explanation Given data: A person pulls a child in a wagon. The rope handle is inclined upward at an angle of 60 ° . The tension in the handle ( F ) is 20 N. The angle made by the rope handle with the horizontal displacement of the wagon ( θ ) is 60 ° . The distance pulled by the person ( d ) is 100 m. The person pulls the child at a constant speed. Formula used: From the given data, the person pulls the wagon at an angle of 60 ° to the horizontal displacement. Refer to the equation (10.6) in the textbook, and modify the expression for work done by the person to pull the child in a wagon as follows. W = F d cos θ (1) Here, F is the tension in the handle, d is the distance pulled by the person, and θ is the angle made by the rope handle with the horizontal displacement of the wagon
