OABCD is a rectangle-based pyramid. The picture on the right is the bird's-eye View from above. Point A is on the xaxis (red), and is 2 meters east of 0. Point C is on the y-axis (green), and i51 meters north of 0. Each unit isl meter. The pyramid is 6 meters tall. (a) A box moves from point A to B, while a horizontal force along the x-axis (from west to east) is pushing it with a magnitude of 10 Newton. How much work is done on the box by this force? Explain.
