Two blocks are attached to opposite ends of a string that passes over a massless, frictionless pulley as shown in the figure below. Block A of mass 11.1 kg lies on a 60.0o incline with a coefficient of friction of 0.545, and block B of mass 1.06 kg is attached to a vertical spring of force constant 210 N/m. The blocks are initially at rest with the spring at equilibrium. Find the maximum height that block B rises.
