1. The problem statement, all variables and given/known data A person is pushing an object of mass m along the ground with force F. The coefficient of kinetic friction between the object and the ground is (mu)k. The object is accelerating, but then the person stops pushing and the object slides to a halt. The person then starts push8ing again with a force F, but the object doesn't budge. The maximum coefficient of static friction between the object and the ground is ms. Which of the following statements is true? Choices: F > (mu)k/(mu)s (mu)kmgsmg (mu)smg=F The scenario described is physically impossible. 2. Relevant equations I read through this again and again and couldn't figure it out at all. I think the last one is possible but I am not sure. 3. The attempt at a solution This is a thinking problem... no equation needed. I am finding the equation. Thoughts? What do you think it is???
