Ariver flows down towards a lake along an incline. initially the river is 90 m above the lake flowing at a rate of 3 m/s. at the lake the velocity is 0 m/s. you are interested in the change of total energy per unit mass of the water. draw a schematic of the system, clearly identifying the system, and determine the change of total energy per unit mass of the water between the inlet and outlet of the system. assume that the internal energy of the water remains constant and that the pressure at the inlet and outlet is the same.

During spring semester at mit, residents of the parallel buildings of the east campus dorms battle one another with large catapults that are made with surgical hose mounted on a window frame. a balloon filled with dyed water is placed in a pouch attached to the hose, which is then stretched through the width of the room. assume that the stretching of the hose obeys hooke's law with a spring constant of 89.0 n/m. if the hose is stretched by 5.80 m and then released, how much work does the force from the hose do on the balloon in the pouch by the time the hose reaches its relaxed length? unitst 3 number-1497 the tolerance is +/-5% open show work click if you would like to show work for this question:
