🧠 Constant-Velocity Pull at 45° — Force Balance, Then Work

Read the question. A  block is pulled along a rough horizontal surface by a force at  above horizontal. Friction coefficient . Block moves . Find the work done by the applied force (standard interpretation, since the question mentions only the displacement).

Standard reading: the block is in equilibrium (constant velocity), so the horizontal component of  balances friction, and the vertical component of  reduces the normal force.
