A crate of mass 140 kg is being pushed by a person across a, Ask an Expert

Academics

A crate of mass 14.0 kg is being pushed by a person across a horizontal floor. The coefficient of static friction among the crate and the surface is 0.350, while the coefficient of kinetic friction is 0.227. The person starts to push, however the crate does not move. The person increases their pushing force until abruptly it begins to move across the floor. What is the acceleration of the crate at the moment it begins to move?
