A motorcycle, which consists of an initial linear speed of 6.2 m/s, decelerates to a speed of 1.6 m/s in 5.9 s. Each wheel consists of a radius of 0.69 m and is rotating in a counter-clockwise (positive) direction. Determine
i) The constant angular acceleration, in rad/s squared, and
ii) The angular displacement, in rad, of each wheel?
