A 75 kg ladder that is 3.0 m in length is placed against a wall at an angle theta. The center of gravity of the ladder is at a point 1.2 m from the base of the ladder. There is no friction between the wall and a the ladder. If the angle theta is 60 degrees,

a) what is the net force on the ladder?

b) What is the net torque on the ladder?

c) what is the vertical force of the ground on the ladder?

d) what is the static frictional force between the floor and the ladder?
