A horizontal force \( F=40 \mathrm{lb} \) is applied to the \( 220-\mathrm{lb} \) refrigerator as shown. The coefficient of kinetic friction at \( A \) and \( B \) is \( \mu_{k}=0.1 \). Assume that the refrigerator moves without tipping. Determine the magnitude of the refrigerator's acceleration, \( a_{G} \). Express your answer to three significant figures and include the appropriate units. \( a_{G} \) \[ = \] Part B Determine the normal force exerted on the refrigerator by the floor at \( A, N_{A} \), Determine the normal force exerted on the refrigerator by the floor at \( B, N_{B} \). Express your answer to three significant figures and include the appropriate units.
