Physics 11

posted by on .

Two people start running from rest. The first person has a mass of 59 kg and is wearing
dress shoes with a coefficient of static friction of 0.52. The other person is wearing
running shoes with a coefficient of static friction of 0.66.
Explain why we do not really need the mass of either person when finding the initial maximum possible acceleration.

    force=mass*acceleration
    mu*mg=m*a

    a=mu*g

    oh...
    thank you
