Transcribed Image Text:10. To meet a U.S. Postal Service requirement, employees' footwear must have a coefficient of
static friction of 0.5 or more on a specified tile surface. A typical athletic shoe has a coefficient
of static friction of 0.800. In an emergency, what is the minimum time interval in which a person
starting from rest can move 3.00 m on the tile surface if she is wearing (a) footwear meeting the
Postal Service minimum and (b) a typical athletic shoe? Answers: a) 1.11 s b) 0.875 s
