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.
