Dexter Eius is running through the cafeteria when he slips on some mashed potatoes and falls to the floor. (Let that be a lesson for Dexter.) Dexter lands in a puddle of milk and skids to a stop with an acceleration of -5.17 m/s/s. Dexter weighs 707.0 Newtons. Determine the coefficient of friction between Dexter and the milky floor.
Mila and Penelope are re-modeling their dorm room. They wish to move a 89.6-kg sofa from one wall to the opposite wall. It takes 466-N of force to start it in motion. Calculate the coefficient of static friction between the floor and the sofa.
