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 dimensions are shown in the figure. Express the results in terms of given quantities: m, g, h and u. 1) Let u = 1/5. After separation from W, U continues to fall. Find velocity v1 of U when it impacts the ground. 2) Let u = 1/5. After separation from U, W keeps sliding. How far will it get? Specifically, what is the final distance between the point D of W and the vertical wall?

Question
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
dimensions are shown in the figure. Express the results in
terms of given quantities: m, g, h and u.
1) Let u = 1/5. After separation from W, U continues to fall. Find velocity v1
of U when it impacts the ground.
2) Let u = 1/5. After separation from U, W keeps sliding. How far will it get?
Specifically, what is the final distance between the point D of W and the vertical wall?
