Body U with mass 5m is stacked on the top body W with mass m, and released. The bodies are in contact along the frictionless interface at 45 to the vertical. The body U is in contact with the frictionless vertical wall. Body W lies on the floor with coefficient of friction u. Relevant h dimensions are shown in the figure. Express the results in U: 5m terms of given quantities: m, g, h and µ (except when u is given numerically).
