Consider a plane that is inclined by an angle of 45 degrees with the horizontal. A block of mass 5 kg starts at rest at the top of the inclined plane, at a height of 2 meters above the ground. The surface of the plane and the block have a relative coefficient of friction of (μk= 0.1). If the block is allowed to slide down the plane. (a) What is the work done by gravity during the slide down the plane? (b) What is the work done by friction during the slide down the plane? (c) Using the information from (a) and (b), find the speed of the object when it reaches the ground?
