Rockets can be spin-stabilized; that is, they can fly straighterthrough space if they rotate around their long axis. Generally, 1rotation per second is a good angular speed forspin-stabilization.
a. Assume the rocket acts like a solid cylinder. The rocket hasa mass of 30000 kg (almost all of it fuel) and a radius of 1.00 m.Calculate the angular momentum of the rocket as it spins. Payattention to units.
b. A problem arises because fuels for larger rockets are liquid.Due to the centripetal effect, the fuel is pushed to the outer skinof the rocket. So now the rocket acts more like a thin-walledhollow cylinder with a mass of 30000 kg and a radius of 1.00 m.Calculate the new angular velocity of this rocket, assuming that itis the same rocket as in part a. Describe what happened to therocket’s spin.
