You are given the dynamics equations that are used to solve a
problem:
(100N) cos30∘−fk=(20kg)ax
n+(100N)sin30∘−(20kg)(9.80m/s2)=0
fk=0.20n
You wish to pull a 20 kg wooden crate across a wood floor (μk = 0.20) by pulling on a rope attached to the crate. Your pull is 100 N at an angle of 30∘ above the horizontal. What will be the acceleration of the crate?

You are a fitness trainer developing an exercise that involves pulling a heavy crate across a rough surface. You attach a rope to a crate of mass M = 45.0 kg and place it on a carpeted track. Using your physics expertise, you have already determined that the coefficient of kinetic friction between the crate and the carpet is μk = 0.430. To test the apparatus, you have one of your employees pull on the rope as hard as she...
