Draw the free body diagram for the box and the cart separately.
Including a Cartesian coordinate axis and the direction of the acceleration.

A \\( 50 \\mathrm{~kg} \\) box is placed on a \\( 35 \\mathrm{~kg} \\) cart pulled by a force as shown in the figure. The coefficient of static friction between the box and the cart is 0.45 and the coefficient of kinetic friction between the cart and the ground is 0.28 .
