help me pls. it's for my homework in physics. 1. Two crates of mass 75kg and 110kg are in contact and at rest on a horizontal surface. A 620N force is exerted on the 75kg crate. If the coefficient of kinetic is 0.15, calculate: (a) the acceleration of the system, and (b) the force that each crate exerts on the other. 2. Determine the acceleration of the object moving down a plane.

ok.. two steps first step.. consider the two objects to be one big object, work out the forces and calculate the acceleration.. second step.. since each crate experiences this same acceleration, find the forces on each one.. can you try now?
