Two identical 19.1?kg spheres of radius 12.7cm are 35.7cm apart (center-to-center distance). Assume that the only force acting on each mass is the gravitational force due to the other mass.

a) If they are released from rest and allowed to fall toward one another, what is their speed when they first make contact?

b) If the spheres are initially at rest and just touching, how much energy is required to separate them to 1.39m apart?
