[填空题]
In traveling to the Moon, astronautsceo3jqsgv lx+; . )(rz aboard the Apollo spacecraft pkwv3b4wly30 put themselves into a slow rotation to distribute the Sun’svpy 304wbwk3 l 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 8.5 m. Determine
(a) the angular acceleration, $\approx$ $rad/s^2$
(b) the radial and tangential components of the linear acceleration of a point on the skin of the ship 5.0 min after it started this acceleration. $a_{tan}$ = $ \times10^{ -4}$ $m/s^2$ $a_{rad}$ = $ \times10^{ -3}$ $m/s^2$
