16. Running without friction is impossible. In fact, to maximize your acceleration, you need to maximize the static friction between your shoes and the floor. a) Explain why static friction is necessary for running or walking. requirement, employees' shoes must have a coefficient of static friction of 0.5 or more on a specified tile surface. In an emergency, what is the minimum time interval in which a postal worker starting from rest can move a distance of 3 m on the tile surface? c) A typical athletic shoe has a coefficient of static friction of 0.8 when used on a running track. What is the minimum time interval in which an athlete starting from rest can move a distance of 100 m on a running track? b) To meet a U.S. Postal Service
Two long straight wires carry currents perpendicular to the xy plane. One carries a current of la = 17 A and passes through the point x = 5 cm on the x axis. The second wire has a current of Ig = 56 A and passes through the point y = 8 cm on the y axis. What is the magnitude of the resulting magnetic field at the origin? Write your answer in micro-tesla.
