A spherical mass M is held fixed in deep space, well away from the earth's gravitational pull. A second mass m is released from rest at a distance r0 from M and begins to move toward M with an initial acceleration a0. In terms of a0, what is m's acceleration when the two masses are only r0/16 apart

explanation:

the masses of the objects and the distance between them

this means that the temperature of both substances will be equal
