Under the man's pushing force P= 34.8 lb, the uniform cabinet is sliding on the ground with a constant acceleration of a. If the uniform cabinet has weight of 150 lb, and the coefficient of kinetic friction between the cabinet and the ground is μk = 0.12, determine the normal force reaction under leg A. Please pay attention: the numbers may change since they are randomized. Your answer must include 2 places after the decimal point and proper unit. Take g = 32.2 ft/s². -1 ft- -1 ft- Your Answer: Answer P 4 ft units A 3.5 ft B
