Describe the remaining forces you have indicated above in a similar fashion.
The diagram you have drawn is called a free-bodydiagram.A free-body diagram should show only the forces exerted on the object or system of interest (in this case, forces exerted on the block). Check your free-body diagram and, if necessary, modify it accordingly.
A proper free-body diagram should not have anything on it except a representation of the object and the (labeled) forces exerted on that object. A free-body diagram never includes (1) forces exerted by the object of interest on other objects or (2) sketches of other objects that exert forces on the object of interest.

- b. A block of mass m is placed at rest on an inclined plane as shown below. The plane is frictionless and makes the angle with the horizontal as shown. If another force of magnitude P is applied to the block at the known angle as shown, draw the free body diagram for the block and determine what the value of P must be if the block is to remain at rest.

Once block B is set into downward motion it descends at a constant speed. Assume that the mass and friction of the pulley are negligible. Calculate the coefficient of kinetic friction u between block A and the table top. Express your answer in terms of some or all of the variables WA (double-u subscript A), WB, and g (the acceleration due to gravity).arrow_forwardDraw a free body diagram (fbd) for m1 for the case where it is released from rest. Use the notation shown in class, F 2on 1. Draw your force vectors to scale so you can tell the direction of m1’s acceleration is to the right. Clearly indicate which direction you are choosing as positive for the horizontal and vertical directions. Write out the two equations from Newton’s Second Law (F = ma), one for each direction. Denote your x-equation as equation (1) and your y-equation as equation (2). No need to solve for anything just yet. Use your fbd diagram of m1 to determine which force and which object is trying to horizontally accelerate m1. Which force and which object is trying to prevent this acceleration? Which of these two forces is larger? Draw a fbd for m2. Clearly indicate which direction you are choosing as positive for the vertical direction. Also be sure that the force vector arrows are drawn to scale so that you can tell that m2 is accelerating down. Use Newton’s Second Law to…arrow_forward

The second acts on the body at an angle 0 measured from horizontal, as shown. If necessary, use Fs and Fk for the forces of static and kinetic friction. L.
