sorry someone can help me with this problem about the revolutions of the plate?? thanks! A small block B rotates with the horizontal plate A in Fig. the distance between the block and the axis of rotation is r = 100 mm, the angular acceleration of the plate is α = 2 rad/s2 = constant and the initial angular velocity is zero. calculate and graph. a) the magnitude of the acceleration AB block as a function of rotation angle θ for the first two revolutions of the plate. b) the φ angle formed by the acceleration of the block AB with OB radius as a function of rotation angle θ for the first two revolutions of the plate.
