A 5 kg bag of sand is poured into a funnel and allowed to flow out the bottom of the funnel and onto a scale that is 2.8 m below, where the sand collects. If it takes 11 seconds for all of the sand to flow out of the funnel, what does the scale read 8 seconds after the sand begins collecting? State your answer to the nearest 0.1 N. (Let g= 10 m/s2)
The bottom of a car hits a sharp rock, which punctures a small hole on the bottom of its gas tank. If the height of the gasoline in the tank is 30 cm and the surface of the gas in the tank is exposed to atmospheric pressure (since the lid is not tightly sealed), determine the initial velocity of the gasoline pouring out of the hole. Answer in m/s.

Water flowing at 1.88 m/s will leave the end of a horizontal channel at the top of a vertical wall h = 2.85 m high, and from there it will fall into a pool (see the figure below). (a) The architect has asked you to determine if the space behind the waterfall will be wide enough for a pedestrian walkway. (Enter the maximum width, in meters, of a walkway behind the waterfall.) (b) To sell her plan to the city council, the architect wants to build a model to standard scale, which is one-twelfth actual size. She asks you to design and build the model, with the important question being: how fast (in m/s) should the water flow in the channel in the model? m/sarrow_forward
