Prior to being placed in its hole, a 5700-N, 9.0-m-long, uniform utility pole makes some nonzero angle with the vertical. A vertical cable attached 2.0 m below its upper end holds it in place while its lower end rests on the ground.
(a) Find the tension in the cable and the magnitude and direction of the force exerted by the ground on the pole.
(b) Why don't we need to know the angle the pole makes with the vertical, as long as it is not zero?
