Prior to being placed in its hole, a uniform utility pole of weight 5630 N and length 9.1 m makes some nonzero angle with the vertical. A vertical cable attached a distance 2.5 m below its upper end holds it in place while its lower end rests on the ground.
Find the tension in the cable.
Find the magnitude of the force exerted by the ground on the pole.
Find the direction of the force exerted by the ground on the pole.
