A 75 kg mail cart traveling at 6.0 m/s to the left when it collided with Mr. Tate, who is at rest. If the mail cart comes to a complete stop, what is Terry's velocity immediately after impact?

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) ! : )
