Choose the ending that best completes the following sentence: if an object is traveling with a constant velocity… a. there are no forces on the object. b. there is no net force on the object. c. there are no forces parallel to the direction of motion. d. there are only forces parallel to the direction of motion

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) ! : )
