space ship wall rockets FIGURE 2 Given the moment of inertia of cylindrical space-ship is MR². If each rocket provides a constant force of 50 N, how long will it take to stop the rotation? d) A hamster running in an exercise wheel. Typical hamsters are 320 g and can run at speeds of 2.8 m s'. The exercise wheel has a moment of inertia about its centre of 0.22 kg m? and the radius of the wheel is 10.0 cm. How fast should the wheel have been rotating? Treat the hamster as a point mass.
