A rotating disk of moment of inertia I and angular velocity ? is dropped on an identical disk rotating with angular velocity 3•?. Use symbols in this problem. They stick together after the collision.a. Assuming no external torques, what is the final angular velocity ? of the two disks after the collision?b. What is the kinetic energy of the system before the collision?c. What is the kinetic energy of the system after the collision?d. Using symbols, write the expression for the heat energy
