A drum rotates around its central axis at an angular velocity of 19.5 rad/s. If the drum then slows at a constant rate of 5.49 rad/52, (a) how much time does it take and {b} through what angle does it rotate in coming to rest? (a) Number n Units V (b) Number n Units v Calculate the rotational inertia of a meter stick, with mass 0.612 kg. about an axis perpendicular to the stick and located at the 35.1 cm mark. (Treat the stick as a thin rod.) Number n Units v The uniform solid block in the figure has mass 48.0 kg and edge lengths a = 0.549 m, b = 1.89 m, and c = 0.145 m. Calculate its rotational inertia about an axis through one corner and perpendicular to the large faces. Rotation axis -a- Number UnitsThe angular position of a point on a rotating wheel is given by 0 = 7.35 + 3.17t2+ 1.6913, where 0 is in radians and t is in seconds.
