A crate of mass \(m\) rests on a rough horizontal floor. The coefficient of kinetic friction between the crate and the floor is \(\mu_k\). A student applies a horizontal force to the right to push the crate. The graph below shows the velocity \(v\) of the crate as a function of time \(t\). The motion is divided into three distinct intervals. In the interval from \(t_2\) to \(t_3\), the student stops pushing the crate entirely, and it coasts to a stop. • Nerd Notes
