Suppose both cups are poured at the same time, and both are left sitting in the room that is 75°f. but this time,
milk is immediately poured into cup 2, cooling it to an initial temperature of 162°f.
a. use newton’s law of cooling to write equations for the temperature of each cup of coffee after tt minutes has
elapsed.

The equations of both cups after t minutes is given by:

Step-by-step explanation:

The complete exercise says:

Two cups of coffee are poured from the same pot. The initial temperature of the coffee is 180°F, and is 0.2337 (for time in minutes).

Newton's law of cooling:

where,

= room temperature

= initial temperature

k=cooling constant

Hence,

Cup 1:

= 75 °F

= 180 °F

Cup 2:

= 75 °F

= 162 °F
