H answer each question with explaination and good handwriting please thanks. Basically these are the answers but my question is how did he get there

14. In the gure to the right, two boxes of masses 2m and 5m are in contact with each other on a frictionless surface. A force, F, is applied to 2m. Answers to the following questions should be in terms of F and m a) What is the acceleration of the more massive box? b) What is the force causing the acceleration of the more massive box (the net force on 5m)? F 5 m c) What is the force exerted on the smaller box by the larger box? (1) What is the net force on the smaller box? e) Show all the forces acting on each box below. Indicate the action reaction pairs of forces for all the forces acting on the boxes. 1) Answer parts a)-d) if there is friction between the blocks and the table and the coefficient of kinetic friction is ,uk. Answers should be in terms of F, m, ,le and g 1. a) 9.90kg b) 3.78 kg 12. a = 1.96 m/s2; Tleft = 23.5 N; Tright = 47.0 N 13. A=1.01m/s2, FT=15.9 4. a) F/7m b) 5/7 F c) -5/7 F d) 2/7 F f) a=3.03m/s2, Fnet on 4m=24.3N, -40 N, Fnet on m=6.08N
