2. For the 50-kg cart shown below, a force P of 400 N is required for transportation. Using the Dynamic Equilibrium method, calculate the acceleration of the cart. In addition, determine the reactions at A and B under these conditions. Assume that the center of mass is located at G (50 marks). 30° G. 0.4 m 2 0.08 m 0.3 m 0.2 m -| 0.3 m
