Example Question:
A box of mass 5 kg is at rest on a rough horizontal floor. (i) Find the value of the normal reaction of the floor on the box. The box remains at rest on the floor when a force of 10 N is applied to it at an angle of 40° to the upward vertical, as shown in the diagram: (ii) Draw a diagram showing all the forces acting on the box. (iii) Calculate the new value of the normal reaction of the floor on the box and also the frictional force. media type="custom" key="14216580"
