Solve Question 2A simple problem of pradical importance that illstrates the nature of fricion is the study of the initiafion of motion ofan object on a rough surface. For the purpose of this example, lefs look at what happens when a person pushes acrate of mass m on a rough floor as shown in Figure 2. Letting u, and u, with u. < pn, be the static and kinetic frictioncoeffcients between the crate and the ground, respe ctively, consider a case in which the force P() = Pat. For thiscase, determine the time at which the moton begins and the friction force as a function of time.Figure 2: A person pushing a crate of mass m over a rough surfacewith a time-dependent force PI)
