A construction worker pulls on a crate of mass, m, on level ground via a light, uniform cable that is attached to the crate at an angle, 0, above the horizontal. As a result of the force applied by the worker, the cable acquires a tension, T. What is the normal force of the ground on the crate? Neglect friction between the crate and the surface. (See the diagram below.) T Crate m a. mg - Tsine O b.mg + Tsin® O c. mg + Tcose O d. mg e. mg - Tcose
