The 10 kg block A is on an inclined plane with 0 = 30° as shown in the figure below. The block is attached to a spring with spring constant 100 N/m which at the instant shown is in its equilibrium position (unstretched, uncompressed). The coefficient of kinetic friction between the block and the inclined plane is µ=0.8. The block is given some initial velocity v, up the incline. It travels up the incline to some maximum height, then reverses, travels down the incline and comes to rest exactly where it started from. Recall that we refer to the kinetic and potential energies of a body as mechanical energies. 1. Consider the first stage of motion (from the initial position of the block to the point where it stops up the incline). a. Draw a large, clear diagram for the instant that the block stops. Include all notation that you introduce to describe the problem at this instant. b. Determine mechanical energies of the block at its starting and stopping points. c. Write down the equation that relates the mechanical energies at the two points.

Select the correct statements regarding the addition of moments. (Select 3) Moments have directions, so a negative value implies it is along the opposite direction from the reference direction. All the moments need to have the same reference point/pivot in order to add together. Calculate each moment by multiplying each force with its distance to the reference point, and add all values together, regardless of their direction. You have to define the reference direction first, either clockwise or counter-clockwise.
