To solve the problem it is necessary to apply the concepts related to the Centripetal Force.
By definition the centripetal force is given by

Our values are defined by

Therefore replacing in the equation we have to,


Re-arrange to find V,


Therefore the expected velocity of the spinning mass at the new radius is 1.35m/s
Answer:
It depends on where the temperature is dropping, in which body so to speak. Generally, the temperature adapts to the two bodies, for example if a hot piece of metal meets a cold one, the two will continue until they are at an equal temperature, an intermediate temperature.
