Figure P18.16 shows a 1000-kg mass being lowered by a cable at a uniform rate of 4 m/s from a drum of 550-mmdiameter weighing 2.5 kN and having a 250-mm-radius of gyration.

(a) What is the kinetic energy in the system?

(b) The uniform rate of descent is maintained by a brake on the drum which applies a torque of 2698 N m. What additional brake torque is required to bring the system to rest in 0.60 s?
