You are designing a slide for a water park. In a sitting position, park guests slide a vertical distance h down the water-slide, which has negligible friction. When they reach the bottom of the slide, they grab a handle at the bottom end of a 6.00-m-long uniform pole. The pole hangs vertically, initially at rest. The upper end of the pole is pivoted about a stationary, frictionless axle. The pole with a person hanging on the end swings up through an angle of 72.0∘, and then the person lets go of the pole and drops into a pool of water. Treat the person as a point mass. The pole’s moment of inertia is given by I=1/3ML^2 where L = 6.00 m is the length of the pole and M = 31.0 kg is its mass. For a person of mass 70.0 kg, what must be the height h in order for the pole to have a maximum angle of swing of 72.0∘ after the collision?

You have been hired by a company that is designing a new slide (Chorrera) for an aquatic amusement park. In the conceptual design, a customer is expected to go down the curved end slide and then move horizontally across the bottom. At the end of the slide, the client grasps the end of a 16.0 m long vertical bar that can rotate around its center. After holding on to the bar, the client falls into a pool. When the bar...

6. A water slide can be considered to be frictionless. The top of the slide is 4.2 m above the bottom of the slide. Riders exit the slide with a horizontal velocity. The bottom of the slide is 1.5 m above the water. A certain rider has a mass of 27 kg. A. Sketch the situation at the top of the slide, bottom if the slide, and just before they hit the water. B. What is their gravitational potential energy...

You are designing a system to add CO2 to water to make carbonated water (sparkling water, like Club Soda or Perrier). If the gas pumped into the bottle above the water is at a pressure of 2 atmospheres and is composed of 100% CO2, what is the equilibrium concentration of dissolved CO2 in the water? If the pH of the water is 5.0, what is the concentration of CO3^-2, HCO3-, and H2CO3 ? (KH=0.0334 mol/L*atm) CO2(aq) + H2O<-----> H2CO3 H2CO3...
