Three boxes are being pushed across a frictionless surface by a horizontal force of size 284 N. Box 1 has mass 27 kg, box 2 has mass 8 kg, and box 3 has mass 18 kg. Calculate the normal force that box 1 exerts on box 2, in N. Make sure your answer is a positive number. This scenario is depicted below. (Please answer to the fourth decimal place - i.e 14.3225)
