After sitting in a refrigerator for a while, a turkey at a temperature of 40°F is
placed on the counter and slowly warms closer to room temperature (73°F).
Newton's Law of Heating explains that the temperature of the turkey will
increase proportionally to the difference between the temperature of the
turkey and the temperature of the room, as given by the formula below:
T = Ta + (To – Ta)e kt
Ta =the temperature surrounding the object
То
= the initial temperature of the object
t = the time in minutes
T= the temperature of the object aftert minutes

The number of seconds that it takes a pendulum to swing back and forth once (called its period) is given by
P=1.11.L¹1/2
where L is the length of the cable or chain holding the pendulum, measured in feet.
Suppose you are making a rope swing and want the period of the swing to be 7 seconds. How long should the
rope swing be?
L=
