1PRACTICE PROBLEM
A 35.0 N block is resting on a horizontal floor. The coefficients of static and kinetic friction between the block and the floor are 0.38 and 0.26 respectively. A child is pushing against the block with a horizontal force. Determine the magnitude of the friction force on the crate and its acceleration when the child applies a horizontal steady force of 15.0 N.
