Two crates rest on the floor one next to the other. A man pushes with a horizontal force of 500 N on the larger (50.0 kg), which, in turn, pushes the other (25.0 kg) so that both slide as he walks along. Each crate experiences a friction force opposing the motion equal to 40% of its weight. Determine the acceleration of each crate.
