a dynamic cart is released from rest at the top of a 1.5 meter long incline plane. Using photo-gate timers, the time to reach the bottom of the inclined plane is found to be 2.231 seconds. What was the initial speed of the dynamic cart?

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?
