Far out in space, a 100,000-kg rocket and a 200,000-kg rocket are docked at opposite ends of a motionless 90m-long tunnel. the tunnel is rigid and has much less mass than the rockets. the rockets start their engines simultaneously, each providing 50,000n of constant thrust in opposite directions. a. find the center of mass, as measured from rocket 1b. what is the moment of inertia of the system, assuming the rockets can be treated as point masses? c. find the net torque on the system about the center of massd. what is the angular acceleration of the system? e. what is the structure's angular velocity after 30.0 seconds?
