A skateboarder slides down a frictionless ramp inclined at an angle of 30 degree to the horizontal. He then slides across a frictionless horizontal floor and begins to slide up a second incline at an angle of 25 degree to the horizontal. The skateboarder starts at a distance of 10 meter from the bottom of the first incline. Obtain how far up the second incline will him go if the coefficient of kinetic friction on the second incline is 0.10?
