Question

7. A space telescope is at rest (not rotating) in space. It can have its orientation changed by and radius 0.250m. The flywheel on the side of the telescope. The flywheel is a solid disk of mass 9.0kg moment of inertia of the telescope around the flywheel axle is 4,750kgm' a) When in orbit around the carth, what are the extermal forces on the telescope? Buavitional force Final position 90.0 b) What is the net torque on the telescope due to the forces from part a)? Explain. flywheel Initial position e) How fast will the telescope rotate in rev/min when the flywheel is rotating clockwise at 500rev/min? Start by stating what principle you are applying and why it applies in this case. d) How many minutes must the flywheel rotate at 500rev/min to rotate the telescope from the initial position to the final position shown to the right?
