Two wooden crates with masses are as shown are tied together by a horizontal cord. Another cord is tied to the first crate and it is pulled with a force of 199N at a angle of 20.0 degrees. Each crate has a coefficient of kinetic friction of 0.55 . Find the tension in the ropes between the crates and the magnitude of the acceleration of the system.

The smallest mass is 9.91kg which is attached to the biggest mass of 11.2kg. and the rope is pulled at 20.0 degrees with a force of 199N...
