A gallon of milk in a full plastic jug is sitting on the edge of your kitchen table. Estimate the vertical distance between the top surface of the milk and the bottom of the jug. Also estimate the distance from the tabletop to the floor. You punch a small hole in the side of the jug just above the bottom of the jug, and milk flows out the hole. When the milk first starts to flow out the hole, what horizontal distance does it travel before reaching the floor? Assume the milk is in free fall after it has passed through the hole, and neglect the viscosity of the milk.

- A1.2-m wide cylindrical water tank is filled to the brim. The tank has a hole formed at 13.3 cm above the ground. Water initially leaks out of the hole at a speed 4.2 m.s-1. After some time, it is observed that speed at which water flows out reduces 2.7 m.s-1. During this interval, 3.1 how much water leaked out of the tank, and 3.2 by how much shall the point, at which water lands onarrow_forward83. Blood Flow As blood moves through a vein or an artery, its velocity v is greatest along the central axis and decreases as the distance r from the central axis increases (see the figure). The formula that gives v as a function of r is called the law of laminar flow. For an artery with radius 0.5 cm, the rela- tionship between v (in cm/s) and r (in cm) is given by the function u(r) = 18,500(0.25 – r2) 0srs 0.5 %3D (a) Find v(0.1) and (0.4). (b) What do your answers to part (a) tell you about the flow of blood in this artery? (c) Make a table of values of v(r) for r = 0, 0.1, 0.2, 0.3, 0.4, 0.5. (d) Find the net change in the velocity v as r changes from 0.1 cm to 0.5 cm. 0.5 cmarrow_forward3. On his walk home, Mr. Stark sees a wishing well. He takes out a 100 dollar bill, crumples it up into a ball and throws it upward over the well (at the level of the mouth of the well) and goes up 15 ft. 7 seconds after the bill leaves his hand, it reaches the bottom of the well which apparently didn't have any water after all.

Such differences in arrival times are used as an analytical tool in gas chromatography.arrow_forwardA 15.0 m tall water tower in Mount Pearl, off Wyatt Boulevard, is filled to the top with fresh St. John's tapwater.

A projectile is accelerated through the barrel of a gas gun by gas at high pressure. The acceleration of the projectile is given by a=c/s (m/s) where s (m) is the position of the projectile in the barrel and c is a constant that depends on the initial gas pressure. The projectile starts from rest at s = 1 m and accelerates until it reaches the end of the barrel at s = 2.5 m. a) Determine the value of c for the projectile to leave the barrel with a velocity of 125 m/s. b) (Python) Plot s vs t, v vs t.arrow_forward
