[All sоlutiоns must stаrt by writing аn equаtiоn (or equations) from the equation sheet on your paper. The solution must then follow a logical progression from the equation(s) on the equation sheet to the answer(s).] A 0.75-kg block, starting with a speed of 2.33 m/s, slides 2 m down a frictionless incline, 30 degrees from horizontal. Once on the horizontal, it encounters friction and stops after 3 m. a) Find the force of friction acting on the block using mechanical energy and work principles. Include a labeled sketch (showing the initial and final states you chose as well as the height at which Ug=0), and all work. Enter the size of the force of friction, with units, in the box below. b) What is the coefficient of friction for this region?
