Solve the all parts of given question:

Question: A pair of blocks of the mass M =25.9 kg, and 2 M are dragged over a rough, horizontal surface by two constant forces of magnitude F=72.0 N. The angle is 22.0 °. The blocks are displaced 6.3 m, assume there is no friction between the bottom of the blocks and the floor.

Part A: How many forces are acting on the system made up of both blocks (treat both blocks as one)?

Part B: What is in Newton's the magnitude of the net force acting on the system made up of both blocks?

Part C: What is in Newton's the magnitude of the net force acting on the back block?

Part D: What is in Newton's the magnitude of the force exerted by the front block on the back block?

Part E: What is in Newton's the magnitude of the force exerted by the back block on the front block?

Please show all work and steps to determine the magnitude of the force exerted by the back block on the front block.
