Problem 8 A brick with mass m = 2.0 kg is moved upwards a vertical wall under the influence of a force F→. The force has a magnitude of 40 N and the angle α between the force and the vertical is equal to 35∘ (see Fig. 4). The coefficient of dynamic friction between the brick and the wall is k = 0.25. Find the acceleration of the brick. Please include a free body diagram and a well defined coordinate system in your solution. Figure 4: Object moved up a wall

A block of mass 8 kg is pushed against a wall by a stick that is oriented at and angle 66∘ with the horizontal direction and is being pulled by a vertical string at the same time. The block is moving along the wall with a constant downward velocity. There is kinetic friction between the block and the wall. Given that the normal force exerted by the stick on the block is 43 N and the tension on the block is 37 N. find the coefficient of kinetic friction between the wall and the block, μk, that allows the block to slide with constant velocity. Use g = 9.8 m/s2 and retain your answer to two decimal places. You are encouraged to draw a free-body diagram in your solution, which will provide you with partial credit if you submit your self-grading later.

A block of mass 5 kg is pushed against a wall by a stick that is oriented at and angle 45∘ with the horizontal direction and is being pulled by a vertical string at the same time. The block is moving along the wall with a constant upward velocity. There is kinetic friction between the block and the wall. Given that the normal force exerted by the stick on the block is 69 N and the tension on the block is 24 N, find the coefficient of kinetic friction between the wall and the block, μk, that allows the block to slide with constant velocity.

A person is pulling a large stationary mass of M = 30 kg on a flat surface as shown. Between the floor and M, the static coefficient of friction is μMs = 0.7 and the kinetic coefficient of friction is μMk = 0.3. A smaller stationary mass m = 10 kg is sitting on the top of the large mass; it is secured to the wall by a steel cable as shown. The coefficient of static friction between the surfaces of m and M is μms = 0.6 and coefficient of kinetic friction is μmk = 0.2. If the mass system just about to slip, compute the magnitude of the force F1 that the person must apply. Draw a free body diagram to support your argument, and make sure that your calculation is clear and transparent.
