In Problem you are given the dynamics equations that are used to solve a problem. For the of this, 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 30° − fk = (20 kg)ax
n + (100 N) sin 30° − (20 kg)(9.80 m/s2) = 0
fk = 0.20n
We need at least 10 more requests to produce the solution.
0 / 10 have requested this problem solution
The more requests, the faster the answer.
