SUMMARY
A solid disk of mass m and radius R rolls up an incline without slipping, converting its kinetic energy into potential energy. The relationship between linear velocity v and angular velocity ω is crucial for solving the problem. The final height h reached by the disk is determined to be h = (5/4)(v^2)/g. This conclusion is derived from the energy conservation equation, where the initial kinetic energy equals the potential energy at height h.
