In deep space, sphere A of mass 120 kg is located at the origin of an x axis and sphere B of mass 130 kgis located on the axis at x = 5.8 m. Sphere B is released from rest while sphere A is held at the origin.
a) What is the gravitational potential energy of the two-sphere system now as B is released?
b) What is the kinetic energy of B when it has moved 2.2 m toward A?
