You devise another means of testing the coefficient of friction. You now take block A and have it travel up the bar BC when the angle associated with theta is 30 degrees. Again, given a coefficient of kinetic friction of 0.3, what is the acceleration (in ft/s2) of the block while it is moving?

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?

The slope of a velocity time graph over any interval of time gives the during that interval
