A block with a mass m is pushed up an inclined rough surface by a horizontal force F as shown. If the block is being pushed up at a constant speed, find the magnitude of the applied force F, given that theta =35 degrees , m = 5 kg, and the kinetic frictional coefficient between the block and the inclined surface mu_k = 0.2
A block is pushed onto a frictionless surface of inclination 30 ° by applying a force as shown in the figure. If F = 25 N and M = 3.0 kg, what is the magnitude of the resulting acceleration of the block?
Consider the situation shown in the figure below, except assume that the table is inclined at an angle of 22°, with the pulley at the top of the incline. Does block A slide up or down the incline?

Show that the acceleration of any object down an incline where friction behaves simply (that is, where fk=μkN)fk=μkN) is a=g(sinθ−μkcosθ).a=g(sinθ−μkcosθ). Note that the acceleration is independent of mass and reduces to the expression found in the previous problem when friction becomes negligibly small (μk=0).(μk=0).
As seen in the figure, two objects are connected by a light string that passes over a pulley. Assuming the pulley and incline are frictionless, find the tension in the string. m1 =4 kg , m2 = 10 kg and θ = 480.

In the figure, a 5.50 kg block is sent sliding up a plane inclined at θ = 37.0° while a horizontal force of magnitude F = 55.0 N acts on it. The coefficient of kinetic friction between block and plane is 0.31. What is the magnitude and direction (up or down the plane) of the block's acceleration?
At one moment during a walk around the block, there are four forces exerted upon Fido - a 10.0 kg dog. The forces are: Fapp = 67.0 N at 30.0° above the horizontal (rightward and upward)Fnorm = 64.5 N, upFfrict = 27.6 N, leftFgrav = 98 N, down Resolve the applied force (Fapp) into horizontal and vertical components, then add the forces up as vectors to determine the net force.
An elevator (mass 4850 kg) is to be designed so that the maximum acceleration is 0.0680g. What are the maximum and minimum forces the motor should exert on the supporting cable? In solving it , 1 was added to the acceleration when it was going up and subtracted when it is going down and I am confused on why.
