In Problems 70 through 72 you are given the dynamics equations that are used to solve a problem. For each of these, you are to

a. Write a realistic problem for which these are the correct equations.
b. Draw the free-body diagram and the pictorial representation for your problem.
c. Finish the solution of the problem.

(100 N) cos 30º - f_k = (20 kg)a_x
n + (100 N) sin 30º - (20 kg)(9.80 m/s²) = 0
f_k = 0.20n
