You come across an open container that is filled with two liquids. since the two liquids have different densities, there is a distinct separation between them. water, which has a density of =1.00×10^3 kg/m^3 , fills the lower portion of the container to a depth of 0.218 m . the fluid that is floating on top of the water is 0.307 m deep. if the absolute pressure on the bottom of the container is 1.049×10^5 pa , what is the density, , of the unknown fluid? the acceleration due to gravity is =9.81 m/s2 and atmospheric pressure is =1.013×10^5 pa .

Emmy kicks a soccer ball up at an angle of 45° over a level field. she watches the ball's trajectory and notices that it lands, two seconds after being kicked, about 20 m away to the north. assume that air resistance is negligible, and plot the horizontal and vertical components of the ball's velocity as a function of time. consider only the time that the ball is in the air, after being kicked but before landing. take "north" and "up" as the positive ‑ and ‑directions, respectively, and use ≈10 m/s2 for the downward acceleration due to gravity.

You want to move a heavy box with mass 30.0 kg across a carpeted floor. you pull hard on one of the edges of the box at an angle 30∘ above the horizontal with a force of magnitude 240 n, causing the box to move horizontally. the force of friction between the moving box and the floor has magnitude 41.5 n . what is the box's acceleration just after it begins to move
