2.1 Explain what is meant by a rigid body. 2.2 The definition of a rigid body is usually regarded as an idealised definition, why? What are forces of constraint in rigid A flywheel rotates such that it sweeps out an angle at the rate of 0= wt= (45.0 rad/s)t radians. The wheel rotates counterclockwise when viewed in the plane of the page. 2.3 bodies? 2.4 2.4.1 What is the angular velocity of the flywheel? 2.4.2 What direction is the angular velocity? Explain how it is obtained 2.4.3 through in 30 s? 2.4.4 What is the tangential speed of a point on the flywheel 10 cm from the axis of rotation? How many radians does the flywheel rotate
