You are working as a letter sorter in a U.S Post Office. Postal regulations require that employees' footwear must have a minimum coefficient of static friction of 0.5 on a speci- fied tile surface. You are wearing athletic shoes for which you do not know the coefficient of static friction. In order Screen Shot 2020-10-21 at 01.48.25 Q Search to determine the coefficient, you imagine that there is an emergency and start running across the room. You have a coworker time you, and find that you can begin at rest and move 4.23 m in 1.20 s. If you try to move faster than this, your feet slip. Assuming your acceleration is constant, does your footwear qualify for the postal regulation?
