Question:

For a short time, gear A of the automobile starter rotates with an angular acceleration of α_A = (450t² + 60) rad/s², where t is in seconds. Determine the angular velocity and angular displacement of gear B when t = 2 s, starting from rest. The radii of gears A and B are 10 mm and 25 mm, respectively.
