Draw the free body diagram and determine the reaction forces. I) Two crates, each of mass \( 300 \mathrm{~kg} \), are placed as shown in the bed of a \( 1000 \mathrm{~kg} \) pick-up truck. Totoro's mass is \( 50 \mathrm{~kg} \) and the dashed line pass through its center of gravity. Draw the free-body-diagram needed to determine the reaction at each of the two rear wheels \( A \) and front wheels \( B \).
