A block of mass m = 39 kg is slid over a horizontal frictionless surface at some constant velocity. It then encounters a inclined plane which has a coefficient of kinetic friction of 0.39. The inclination angle for the incline is x = 34.6 degrees and the height of the incline is h = 23.8 meters above its base. If the magnitude of the velocity at the top of incline is 34 m/s for the block, what was the magnitude of its velocity at the bottom of the incline in m/s?
For this one, I really have no idea how to begin. Any help would be really appreciated. Thanks.
