In traveling to the Moon, astronautsbqv 4k(ut, umeha,t 3ilw 72:r aboard the Apollo spacecraft put themselvex-hz4 eb-hwoa:d(7o pb co/ 4js 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 b(oohawz b-x7p4 /c:o4jhd -eminute 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}$ $m/s^2$
