The 150 kg box shown in Figure 2.98 moves 2.27 m horizontally on the ground thanks to the action of a force F of magnitude 248 N pulling it. A friction force of 132 N acts on the box I. Draw a free-body diagram showing all the forces acting on the box. Consider the appropriate size of each vector, label each force, and indicate the object of each force. II. Find the work done by the force F, the friction force, the weight, and the normal force. III. Calculate the net work of each IV. Determine the variation of kinetic energy in the box V. Calculate the power transmitted to the box VI. Explain why it would be easier to move the box if it were pulled in the direction indicated by the dashed line with the same magnitude of force F? VII. When the box is pulled at an angle of 20.0º with respect to the horizontal, the applied force is 204 N. Without calculating how the work of this force compares with the work of the force magnitude 248 N.
