A disc of radius of 10cm rotates from rest with a constant angular acceleration. If it requires 2s for it to rotate through an angular displacement of 60°: (a) find the (c) the linear speed at t = 2s of a point that is at a distance of 7 cm from the center of the disc; (d) the distance that this point has moved during that time interval.
