When mass M is at the position shown, it is sliding down the inclined part of a slide at a speed of 2.27 m/s. The mass stops a distance S2 = 1.9 m along the level part of the slide. The distance S1 = 1.23 m and the angle q = 31.70°. Calculate the coefficient of kinetic friction for the mass on the surface. Having trouble loading image but its basicallya block sliding down a ramp on an angle which levels out. Angle of q is the angle of the slope which the block is sliding down. S1 is the distance it slides, S2 is how far it continues to slide before it stops.
