Suppose a ball of putty moving horizontally with 1kg. m/s of momentum collides and sticks to an identical ball of puffy moving vertically with 1 kg. m/s of momentum. what is the magnitude of their combined momentum? why is their combined momentum not simply the arithmetic sum, 2 kg. m/s?

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?

Ineed the answer to question 1 , i’m desperate
