The cylindrical cam C is held fixed while the rod AB and bearings E and F rotate about the vertical axis of the cam at a constant rate of _{} = 4 rad/s. If the rod is free to slide through the bearings, determine the magnitudes of the velocity and acceleration of the guide D on the rod as a function of _{}. The guide follows the groove in the cam, and the groove is defined by the equations r = 0.25 ft and z = (0.25 cos _{}) ft.

[A].

_{}

[B].

v = cos_{} ft/s, a = 4.00 sin_{} ft/s^{2}

[C].

v = sin_{} ft/s, a = 4.00 cos_{} ft/s^{2}

[D].

v = 1.000 ft/s, a = 4.00 ft/s^{2}
