1) Two crates of mass 20.0 kg and 35.0 kg are pushed up along an incline of 33.0 degrees by a force of 550 N. Coefficients of kinetic friction are 0.25 and 0.37 respectively for the two crates. (a) Draw force diagrams for each of the crates. (b) Calculate the acceleration of the two crates. (c) Calculate the contact force between the two crates. (d) What would be the contact force if the two crates are reversed?

answer; i believe the correct answer is (40,000 j) good luck
