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.
