A horizontal force, F, pushes a box up the edge of a square-based pyramid (length = R = 2 cm) from point U to point T. The pyramid has a base length = Q = 1 cm. The direction of the force is along the diagonal line of the base, same as the direction of Uo. F has a magnitude of 7 Newton. a) b) Find cose using conventional trigonometry. Do not use the dot product. Then, use cose to determine the amount of work done by the F. The unit of work is Joule. Find the coordinate of T and find out UT. Then, supply F. which is F projected onto UT. Do not involve the dot product.
