The Angular Velocity of a 755-G Wheel 15

question 69

Essay

The angular velocity of a 755-g wheel 15.0 cm in diameter is given by the equation ω(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?
