A block of wood with a mass of 50.0 kg starts from rest and slides 15.0 m down the surface of a frictionless ramp. The ramp makes an angle of 30.0 with the horizontal. From the bottom of the ramp, the block slides along a horizontal surface. The coefficient of kinetic friction between this horizontal surface and the blocks is 0.20. How far do they slide along the horizontal surface? Frictionless HK = 0.20 O 22.5 m O 25.3 m O 31.8 m O 37.5 m O 27.8 m
