you and a child are on skates and you give each other a push. if the mass of the child is half your mass, who has the greater acceleration? by what factor?
i know it is the child but im not sure about the factor. im pretty sure the answer has something to do with F=ma (Force=mass*acceleration)
so the bigger acceleration goes to the smaller child, by a factor of 2.
a= M/m * A
