Question

An object of mass m=10 kg is at rest on a rough inclined plane with height h, length 8 m, and which makes an angle of 30° with the horizontal. The object is allowed to move and it stops on a rough horizontal surface, at a distance of d=4 m from the bottom of the inclined plane, as shown in the Fig. The coefficient of kinetic friction on the inclined plane is 0.4. (a) What is the speed of the object at the bottom of the inclined plane point A? (b) What is the coefficient of kinetic friction for the horizontal surface? (c) A spring with a spring constant k=200 N/m placed at a distance of 2 m from point A, calculate the distance (x) that the spring will be compressed by before it brings the mass to rest
