In travelling to the Moon, astronauts aboard the Apollo spacecraft put themselves into a slow rotation to distribute the sun's energy evenly. At the start of their trip, they accelerated from no rotation to 1.0 revolution every minute through a 12-min time interval. The spacecraft c can be thought of as a cylinder with a diameter of 8.5 m. Decide (a) the angular acceleration, and (b) the radial and tangential components of the linear acceleration of a point on the skin of the ship 7.0 min after it started this acceleration.
