For both Tracker experiments, calculate the average vertical acceleration, where the time period is t = 0.10 second to t = 1.00 second. Consider only the magnitude of the vertical velocity in the calculations. Record your results to three significant figures. Comment: How does the average acceleration of the two balls compare to the theoretical value of -9.81 meters/second2, and how do the accelerations of the two balls compare to each other?

The key to stability is feedback between the reservoir and the fluxes into and/or out of the reservoir. assume that the rate of outflow from a reservoir depends on the size of the reservoir according to the following relationship: outflow rate= k x (size of reservoir), where k is a constant. a reservoir of water has a volume of 5000 liters, and the rate of outflow at steady state is 25 liters per minute. what is k? (give both the numerical value and its units.) what is the residence time? what is the relationship between k and the residence time?
