Two identical blocks are heated to different temperatures. The blocks are placed so that they touch, and heat begins to flow bet
ween blocks. The pair of blocks is insulated, so no energy escapes.
Lastly, the temperature of each block is measured again. Which pair of temperatures is possible?

Answer:
The acceleration of the mass is 2 meters per square second.
Explanation:
By Newton's second law, we know that force (), measured in newtons, is the product of mass (
), measured in kilograms, and net acceleration (
), measured in meters per square second. That is:
(1)
The initial force applied in the mass is:
In addition, we know that force is directly proportional to acceleration. If the smaller force is removed, then the initial force is reduced to of the initial force. The acceleration of the mass is:
The acceleration of the mass is 2 meters per square second.
