An 80-kg man is one fourth of the way up a 10-m ladder that is resting against a smooth, frictionless wall. If the ladder has a mass of 20 kg and it makes an angle of 60° with the ground, find the force of friction of the ground on the foot of the ladder.

a. 7.8 x 10^{2} N

b. 2.0 x 10^{2} N

c. 50 N

d. 1.7 x 10^{2} N
