Question

An object is placed on an incline with friction. The incline is slowly raised from a zero degrees and at 29.2 degrees, the object begins to slide down the incline. The incline is then raised to 40.5 degrees and the object is placed back on the incline. The coefficient of kinetic friction is one half of the coefficient of static friction and the object slides from rest a distance of 8.7 meters down the incline. It then encounters a horizontal surface at the bottom of the incline with the same coefficient of kinetic friction as the ramp and stops after some distance due to friction. What distance does the object slide on the horizontal surface in meters?
