= 4.2 m and The Hubble space telescope can be approximated as

= 4.2 m and The Hubble space telescope can be approximated as a cylinder with diameter D moment of inertia / = 7.72 x 10 kg m. The telescope is initially at rest, and a reaction motor applies a force of 19 N tangentially to the outer surface of the cylinder for 4.5 s. A. What is the angular acceleration of the telescope? B. What is the average power exerted by the motor over this entire 4.5 s interval? C. What is the instantaneous power exerted at t = 3 s?
