4.1 How does Newton's 1" law apply to rotational motion? Provide example. 4.2 A thick disk is released from rest on an inclined platform without slipping. Given raisk = rm, weightaisk = W N, and = 30, determine: i) the minimum , compatible with this motion, ii) the acc. of the center G, after the disk has rolled 10 m. iii) the vel. of the center G if the disk were to move 10 m down a frictionless 30 inclined.
