You are planning on installing a new above-ground swimming pool in your backyard. The pool will be rectangular with dimensions 32.0 m x 10.0 m. It will be filled with fresh water to a depth of 2.20 m. In order to provide the appropriate structural support, you wish to determine the following. (a) Determine the force exerted on the bottom of the pool by the water (in N). (No Response) N (b) Determine the force exerted on each end of the pool by the water (in N). (Assume the end is the 10.0 m wall.) (No Response) N (c) Determine the force exerted on each side of the pool by the water (in N). (Assume the side is the 32.0 m wall.) (No Response) N (d) You wish to have swimming parties with your children and grandchildren. At a given time, you might have 23 people with an average mass of 75.0 kg in the pool. You need to determine if such parties will affect your calculations for the required strength of materials supporting your pool. The parties will not affect the required strength since…

The construction of a water pistol is shown in the figure below. The cylinder with cross-sectional area A₁ is filled with water and when the piston is pushed (by pulling the trigger), water is forced out the tube with cross-sectional area A2. The radius of the cylinder and tube are, respectively, 1.30 cm and 1.10 mm, and the center of the tube is a height h = 3.00 cm above the center of the cylinder. (Assume atmospheric pressure is 1.013 × 105 Pa.) A2 A₁ (a) If the pistol is fired horizontally at a height of 1.30 m, determine the time interval (in s) required for water to travel from the nozzle to the ground. Neglect air resistance. (No Response) s (b) If the desired range of the stream is 7.50 m, with what speed ✓2 (in m/s) must the stream leave the nozzle? (No Response) m/s (c) At what speed v₁ (in m/s) must the plunger be moved to achieve the desired range? (No Response) m/s (d) What is the pressure (in Pa) at the nozzle? (No Response) Pa (e) Find the pressure (in Pa) needed in the…

A high-speed lifting mechanism supports a(n) 700-kg object with a steel cable that is 34.0 m long and 4.00 cm² in cross-sectional area. (a) Determine the elongation of the cable. (Enter your answer to at least two decimal places.) (No Response) mm (b) By what additional amount does the cable increase in length if the object is accelerated upwards at a rate of 2.5 m/s²? (No Response) mm (c) What is the greatest mass that can be accelerated upward at 2.5 m/s² if the stress in the cable is not to exceed the elastic limit of the cable, which is 2.2 × 108 Pa? (No Response) kg
