Q. Two identical 19.8-kg spheres of radius 12.00 cm are 29.20 cm apart (center-to-center distance).

(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 necessary to separate them to 1.03 m apart? Assume that the only force acting on each mass is the gravitational force as a result of the other mass.
