1. The problem statement, all variables and given/known data 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 Mass1= 59 kg μ1= 0.52 μ2= 0.66 V1i=V2i= 0m/s Mass2[\B] =? 2. Relevant equations Ff=μFn d= vit+1/2at^2 3. The attempt at a solution mass is not needed because the initial velocity of the two people is 0m/s, but when I calculated the acceleration of the first person the acceleration is not equal to zero.
