Homework Statement
My physics classes were a long time ago, and I can't for the life of me remember how to solve this problem: If I have two spheres s1 and s2 touching, of mass m1 and m2, with radii r1 and r2, and centers c1 and c2, and I have a force Fout normal to the surface of s1, how do I calculate the kinematics of the two spheres? Picture here:
So there is Fout, acting on s1, and there must be F12, normal to the tangent where s1 and s2 meet acting on s2, and s21, opposite to F21, acting on s1, with F12 + F21 = 0; Beyond this, however, I am totally lost as to how to find what F12 and F21 are.
Also, there is no gravity and no friction.
