Two crates, of mass 65 kg and 125 kg, are in contact and at rest on a horizontal surface (see figure). A 650 N force is exerted on the 65 kg crate. The coefficient of kinetic friction is 0.21. Calculate the acceleration of the system. Calculate the force that each crate exerts on the other. With the crates reversed, calculate the force that each crate exerts on the other .
