A 10-kg object starts from rest from the top of 2-meter-tall ramp that is inclined at 40⁰ above the x axis. It slides along the rough surface of the incline with the coefficient of kinetic friction 0.20. Using Energy conservati vation a) Find the speed of the object at point B. Then it continues to move along a rough horizontal surface until coming to rest at point C. b) Find the coefficient of kinetic friction for the horizontal surface between B and C if the object stops at C after moving 5 m.
