(Figure 1)Block 1, of mass m1, is connected over an ideal (massless and frictionless) pulley to block 2, of mass m2, as shown. Assume that the blocks accelerate as shown with an acceleration of magnitude a and that the coefficient of kinetic friction between block 2 and the plane is μ. Find the ratio of the masses m1/m2. Express your answer in terms of some or all of the variables a, μ, and θ, as well as the magnitude of the free-fall acceleration g.

What is the acceleration of the system shown in the figure below when released from rest, if Ma = 6kg , Mb = 15 kg, Ѳ = 30º, and the coefficient of kinetic friction is 0.31? (b) i. When Ma is at rest, what type of friction is it experiencing ? ii. Would the resting friction from part (i) be greater or less than or equal to the friction when Ma is moving ? Give your reason
How do I obtain the limiting frictional force of the setup below? I tried multiplying the normal force to the static coefficient of friction but apparently that was wrong.
Given the following information, how would you find the acceleration of the two block system? "Two blocks with masses m1 and m2 are connected by a massless string and sliding down a plane inclined at an angle ?, as shown in the figure below. The kinetic coefficient of friction between block m1 and the inclined plane is ?2, and ?3 for block m2. You can assume that the acceleration due to gravity is given as ?."
I was given this problem, and I don't really know what to do about the fact that the normal force doesn't equal the weight for this problem. How am I supposed to find the kinetic friction coefficient now? A box of mass 2,463g is on level ground being pulled by a force of 6.41N at angle 47.2 above horizontal. If the block is moving with a constant velocity, what is the kinetic friction coefficient? (Hint: the normal force does not always equal the weight; it does not in this case.)

A body with a mass of 5 kg rests on a rough horizontal table with a coefficient of static friction of 0.9. At a given moment, a horizontal force of 40 N is applied to this body, as shown in the figure. Analyze the propositions and answer the alternative that corresponds to the sum of the correct ones. Adopt g = 10 m/s². (01) With the data presented, we can conclude that the static friction force is 48 N. (02) In the proposed situation, the body will move with an acceleration of 5 m/s2.
