Bob is pulling a box of his toys of mass 15.0 kg along a rough horizontal surface for a distance of 6.00 m. The tension force in the rope is 58.0 N and the angle is 30° with respect to the horizontal. The frictional force on the box is 12.0 N.  How much work is done on the box by the normal force, in Joule? Use g = 10.0 m/s2.

Question

Bob is pulling a box of his toys of mass 15.0 kg along a rough horizontal surface for a distance of 6.00 m. The tension force in the rope is 58.0 N and the angle is 30° with respect to the horizontal. The frictional force on the box is 12.0 N.  How much work is done on the box by the normal force, in Joule? Use g = 10.0 m/s2.

Your answer needs to have 3 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.

In the image, a person is shown pulling a box with a rope. The box is filled with various objects, including toys, a ball, and a baseball bat. The person is exerting force by pulling the rope at an angle, demonstrating the concept of force and motion. The dashed line represents the direction of the force being applied.

This illustration is useful for understanding basic physics concepts such as force, friction, and the effect of different angles on the effort required to move an object. It highlights how the angle of applied force can impact the ease or difficulty of moving the box.
