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. Use g = 9.8 m/s2 and retain your answer to two decimal places.

Drawing free body diagrams a) A book is at rest on a table. Draw a free body diagram showing all forces acting on the book. b) A man pushes a box in the direction of the arrow shown. Draw a free body diagram showing all forces acting on the box. c) Block 1 and Block 2 are hung over a frictionless pulley. Assume Block 1 is sitting on a frictionless surface. Block 1 has a mass of 5.0 kg and Block 2 has a mass of 2.0 kg. Draw a free body diagram for both blocks.
