A block of mass 10 kg slides down an inclined plane that has an angle of 30. If the inclined plane has no friction and the block starts at a height of 2 m, how much kinetic energy does the block have when it reaches the bottom? Acceleration due to gravity is g = 9.8 m/s2.

    No friction present means: Ek = Ep

    So Ek = mgh = 10 * 9.8 * 2 = 196 J
