2. Block A is being pushed up the side of a wall. Kinematics dictates that motion can only be in the y-direction. The block is observed to be accelerating upward at 4 m/s² while the forces shown on the drawing are applied. Some clever engineers made a free-body diagram (below). a. What is the mass of the block? b. What is the normal force, N, that the wall is applying to the block? c. What is the friction force, Fr, that the wall is applying to the block? d. What is the coefficient of friction between the wall and the block?

Learning Goal: To understand the concept of moment of a force and how to calculate it using a vector formulation. Part A A man wishes to spin a merry-go-round in the x-y plane centered at the origin (0.000, 0.000, 0.000). (Figure 1) Because he must pull upward and cannot stand on the merry-go-round, he must apply a force in the direction of the unit vector What are the x, y, and z components of the resulting moment acting on the merry-go-round about the origin?
