The acceleration of an object as a function of time is given by a(t) = (1.00 m/s2)t2. if displacement of the object between time and time t = 2.00 s is 15.0 m, what is the velocity of the object at time t = 0.00 s? a-13.5 m/s b-not enough information is given to determine the velocity of the object at time t = 0.00 s. c-6.25 m/s d-3.75 m/s 1.25 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) ! : )
