Which of the following describes an object in dynamic equilibrium?
O A. A cheetah runs 15 m/s to the south.
B. A cat sits on a bed without moving.
C. A leopard slows down from 10 m/s to 5 m/s.

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) ! : )
