A wheel 1.8 m in diameter rotates with an angular acceleration of 2.0 rad/s2. (Enter the magnitudes.) (a) If the wheel's initial angular velocity is 5.0 rad/s, what is its angular velocity (in rad/s) after 10 s? rad/s (b) Through what angle (in rad) does it rotate in the 10 s interval? rad (c) What are the tangential speed (in m/s) and tangential acceleration (in m/s) of a point on the rim of the wheel at the end of the 10 s interval? tangential speed m/s tangential acceleration m/s²
