A drinking fountain projects water at an initial angle of 50 degrees above the horizontaland the water reaches a maximum height of 0.15 m above the point of exit. Assume air resistance is negligible.a) Calculate the speed at which the water leaves the fountain.b) The radius of the fountain's exit hole is 4.00 x 10^-3 m. Calculate the volume flow rate of the water.c) The fountain is fed by a pipe that at one point has a radius of7.00 x 10^3 m and is 3.00 m below the fountain's opening. The density of water is 1.0 x 10^3 kg/m3. Calculate the gauge pressure in the pipe at this location.
A catapult launches a test rocket vertically upward from a well, giving the rocket an initial speed of81.0m/sat ground level. What is its velocity just before it hits the ground
Water is in the big beaker in the figure on the left. Scale 1 reads 96 newtons, scale 2 reads 531 newtons, and scale 3 reads 0 newtons. The hanging block has a density of 10 × 10^3 kg/m3. To nearest tenth of a newton what does scale 1 read after t..
