The angular velocity of a 755-g wheel 15.0 cm in diameter is given by the equation
?(t) = (2.00 rad/s2 )t + (1.00 rad/s4 )t3.
(a) Through how many radians does the wheel turn during the first 2.00 s of its motion?
(b) What is the angular acceleration (in rad/s2 ) of the wheel at the end of the first 2.00 s of its motion?
(a) 8.00 rad (b) 14.0 rad/s2
