1. Make a sketch of a friction block sliding down the inclined track. Draw and label vectors to indicate the direction of the velocity and the direction of the acceleration.  Also assign a symbol to the mass of the block and label it on the drawing. 2. Draw a free-body diagram of the forces on the block as it slides down the ramp.  Draw the acceleration vector for the block near the free-body diagram.  Choose a coordinate system, and draw the force vectors on your coordinate system (a force diagram). What angles between your force vectors and your coordinate axes are the same as the angle between the ramp and the table?  Determine all of the angles between the force vectors and the coordinate axes. 3. Write down Newton's 2nd law in both the x and y directions.  For any forces that are at an angle to your coordinate system, be sure to consider the components along the x and y axes. Your answer will depend on how you define your coordinate system.   4. Using the equations in step 3,…
