A train is moving parallel and adjacent to a highway with a constant speed of 30 m/s. Initially a car is 50 m behind the train, traveling in the same direction as the train at 44 m/s and accelerating at 2 m/s2. What is the speed of the car just as it passes the train?

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) ! : )

As microwave light travels through a liquid, it moves at a speed of 2.2 x 108 m/s. if the frequency of this light wave is 1.1 x 108 hz, what is the wavelength of this microwave?
