A 2.0-kg object starts from rest from the top of an inclined plane that makes an angle of 30 with the horizontal and has a rise of 0.40 m. It slides down the inclined plane and at the bottom has a kinetic energy of 60 J. Ignore friction and use g = 10 m/s2. What is the speed of the object at the bottom of the inclined plane?
