In traveling 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 during a 12-min time interval. The spacecraft can be thought of as a cylinder with a diameter of 8.3 m .

1) Determine the angular acceleration of a point on the skin of the ship 2.5 min after it started this acceleration.

2) Determine the radial component of the linear acceleration of a point on the skin of the ship 2.5 min after it started this acceleration.

3) Determine the tangential component of the linear acceleration of a point on the skin of the ship 2.5 min after it started this acceleration.
