Two people, one of mass 51.4KG and the other mass of 78.0 KG, sit a distance between of 2.3 metres apart on a low friction sleds with the same friction coefficients.
A)what is the strength of the gravitational force between them?
B) suppose the friction is slowly reduced until one of the people started moving.Which will accelerate first?
C) what would the coefficient of the static friction between the sleds and the ground have to be for gravity to pull the two together?
