When mass M is at the position shown, it is sliding down the inclined part of a slide at a speed of 2.01 m/s. The mass stops a distance S2 = 2.45 m along the level part of the slide. The distance S1 = 1.08 m and the angle theta = 31.9 degrees. Calculate the coefficient of kinetic friction for the mass on the surface.
