A motorcycle, which consists of an initial linear speed of 6.7 m/s, decelerates to a speed of 1.8 m/s in 5.4 s. Each and every wheel consists of a radius of 0.67 m and is rotating in a counter-clockwise (positive) direction.
(i) Determine the constant angular acceleration? (Point out direction by the sign of the angular acceleration.)
(ii) Determine the angular displacement (in rad) of each wheel?
