Let it be a system formed by two particles 1 and 2 of mass m1 and m2, respectively. Show that the position of the center of mass is located at an internal point to the line segment that connects the positions of particles 1 and 2. This result allows us to immediately estimate the position of the center of mass of a two-particle system.
With what force does a homogeneous ball of mass M attract a material point of mass m, located at distance a from the center of the ball (a>R)?
Suppose an object of mass m, initially travelling with a velocity v1, collides with an object of mass m initially at rest. Prove that the angle between the velocity vectors of the two objects of the two particles after the collision is 90 degrees.
