The rod $$OA$$ rotates clockwise with a constant angular velocity of $$6\mathrm{rad}/\mathrm{s}$$. Two pin-connected slider blocks, located at $$B$$, move freely on $$OA$$ and the curved rod whose shape is a limacon described by the equation $$r=200(2?\cos ?)\mathrm{mm}\text{. (Figure 1) }$$ Figure 1 of 1 Determine the magnitude of the acceleration of the slider blocks at the instant $$?=150^{?}$$. Express your answer to three significant figures and include the appropriate units.
