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. Vt Vt = 450 m/s r = 16.5 m Projectile Support arm ω Assume that the moment of inertia, 1, of the support arm and the applied torque, t, are both constant. Also assume that t = 30 000 Nm. a) Compute the angular velocity, w, required for the launch velocity, Vt. b) Determine the centripetal acceleration of the projectile just before it is released. 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. d) What is the work done to move the projectile from rest to the launch velocity? e) What is the power output of the system just before launch?
