A 2.0 kg object starts from rest from the top of an inclined plane that makes an angle of 30 degrees with the horizontal and has a rise of .4m. It slides down the inclined plane and at the bottom has a kinetic energy of 60J. Ignore friction and use g = 10.m/s2. what is the speed of the object at the bottom of the inclined plane?
