Three blocks A, B, and C stand next to each other as shown in the figure. A net force F with magnitude 388.3 N is applied to block C directly and sends the blocks accelerating to the right. Assume there is no friction between the blocks and the ground. The masses of A, B, and C are 8.9 kg, 28.4 kg, and 84.9 kg, respectively. What is the force on block B due to block A (in units of N)?
