IMPORTANT

A uniform circular disc of radius 50 cm at rest is free to turn about an axis which is perpendicular to its plane and passes through its centre. It is subjected to a torque which produces a constant angular acceleration of 2.0 rad s-2. Its net acceleration in m s-2 at the end of 2.0 s is approximately

IMPORTANT

Two identical discs of the same radius R are rotating about their axes in opposite directions with the same constant angular speed ω. The discs are in the same horizontal plane. At time t=0, the points P and Q are facing each other as shown in the figure. The relative speed between the two points P and Q is vr. As a function of time, it is best represented by
