Explanation:

The egg does not break when it hits sheet because it get sufficient time to slow down as the sheet bend inside and apply a force which gradually slows down the egg and Prevent it From Breaking .

The average value of that force is given by  

where change in momentum

time over which this Process occur    

this means that the temperature of both substances will be equal
