Body U with mass 5m is stacked on the top body W withmass m, and released. The bodies are in contact along thefrictionless interface at 45 to the vertical. The body U isin contact with the frictionless vertical wall. Body W lieson the floor with coefficient of friction u. Relevantdimensions are shown in the figure. Express the results interms of given quantities: m, g, h and u. The system moves. Write the condition that the velocities of U and W must satisfy for the two bodies to remain in contact. Consider the fact that this condition must be satisfied as long as the two bodies are in contact. What can you say about accelerations of the two bodies? Using the equations of motion for the two bodies compute the accelerations during the motion while in contact.
