A Wheel Accelerates with a Constant Angular Acceleration Of $4.5 \mathrm { rad } / \mathrm { s } ^ { 2 }$

Short Answer

A wheel accelerates with a constant angular acceleration of $4.5 \mathrm { rad } / \mathrm { s } ^ { 2 }$ from an initial angular speed of 1.0 rad/s .
(a) Through what angle does the wheel turn in the first 2.0 s, and
(b) what is its anqular speed at that time?
