Question 1.1 A prototype of the novel satellite launching system, 'SpinLaunch', was recently tested. The system uses angular acceleration to spin a satellite-carrying projectile up to a supersonic speed and then releases it, tangentially and upward, into the atmosphere. VE V1 = 450 m/s r = 16.5 m Projectile Support arm Assume that the moment of inertia, I, of the support arm and the applied torque, t, are both constant. Also assume that I = 30 000 Nm. a) Compute the angular velocity, w, required for the launch velocity, Vų. [4 marks) b) Determine the centripetal acceleration of the projectile just before it is released. [3 marks) c) Compute the angular acceleration used to spin the support arm and projectile, given that the time required to move from rest to launch velocity is, T = 700 s. [4 marks] d) What is the work done to move the projectile from rest to the launch velocity? [6 marks) e) What is the power output of the system just before launch?
