Question
The coefficient of static friction is 0.800 between the
soles of a sprinter’s running shoes and the level track
surface on which she is running. Determine the maxi-
mum acceleration she can achieve. Do you need to
know that her mass is 60.0 kg?

Solution
You don't need to know the mass
0.8 * g = 0.8*9.8
= 7.848 m/s^2 she will slip at this acceleration
0.8 * g = 0.8*9.8
= 7.848 m/s^2 she will slip at this acceleration
