An egg is drown at a wall and breaks. A second egg is thrown at the same velocity and collides with a bed sheet. The egg does not break. Why does the egg not break when it hits the sheet?

An object with initial temperature 130 ∘ f is submerged in large tank of water whose temperature is 50 ∘ f . find a formula for f ( t ) , the temperature of the object after t minutes, if the cooling constant is k = − 0.2 . remember newton's law of cooling (the rate of change of temperature with respect to time is equal to k times the difference between the temperature of the object and the surrounding temperature) ! : )
