Use the exact values you enter to make later calculations. jack and jill are on two different floors of their high rise office building and looking out of their respective windows. jack sees a flower pot go past his window ledge and jill sees the same pot go past her window ledge a little while later. the time between the two observed events was 4.4 s. assume air resistance is negligible. (a) if the speed of the pot as it passes jill's window is 65.0 m/s, what was its speed when jack saw it go by?

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) ! : )
