A fywheel of diameter 360 mm increases its angular speed uniformly from 10.5 to 11.5 rev/s in 11 s. Determine (a) the angular acceleration of the wheel, (b) the linear acceleration of a point on the wheel rim.
What is the peripheral speed of the tread on a car tyre of diameter 700 mm if the wheel rotates about its axle with an angular velocity of 6 rad/s?
