A cube of mass m is initially at rest at the highest point of an inclined plane, which has a height of 4.2 m and makes an angle of θ = 24° with respect to the horizontal. After letting go of the object, it is found to be traveling at v = 0.75 m/s a distance d after the end of the inclined plane as shown. The coefficient of kinetic friction between the cube and the plane is μ_p = 0.1, and the coefficient of friction on the horizontal surface is μ_r = 0.2.

What is the speed of the cube, in meters per second, just after it leaves the inclined plane?

Find the distance, d, in meters.
