- 1. A hoop of radius 0.30 m and a mass of 0.25 kg is released from rest and allowed to roll down an inclined plane. What is the translational speed (v) of the hoop after dropping a vertical distance of 2.60 m? m/s 160 ssf ssf60Civil and traffic engineers want to design a banked curve on a highway. The curve will have a 1.80 km radius and the highway's speed limit will be 70.0 mph. If every car will travel at the speed limit, what is this curve's ideal banking angle to three significant figures? NB: 1609 m = 1 mile. Hint: be careful with your units. 1.94° 2.62° 4.02° 3.18° 2.95° 15.5°11. A crate of eggs is located in the middle of the flatbed W of a pickup truck as the truck negotiates a curve in the flat road.

- At takeoff, a commercial jet has a speed of 62 m/s. Its tires have a diameter of 0.86 m. a) At how many rev/min are the tires rotating? b) What is the centripetal acceleration at the edge of the tire in m/s^2? c) With what force must be determined 0.75x10^-15 kg bacterium cling to the rim in N? d)Take the ration of this force to the bacterium's weight.The peripheral speed of the tooth of a 10-in.-diameter circular saw blade is 150 ft/s when the power to the saw is turned off. The speed of the tooth decreases at a constant rate, and the blade comes to rest in 9 s. Determine the time at which the total (or resultant) acceleration of the tooth is 130 ft/s?.A rotating space station is said to create artificial gravity—a loosely-defined term used for an acceleration that would be crudely similar to gravity. The outer wall of the rotating space station would become a floor for the astronauts, and centripetal acceleration supplied by the floor would allow astronauts to exercise and maintain muscle and bone strength more naturally than in non-rotating space environments. An example of such a setup are Space Station V and the Discovery from the movie 2001: A Space Odyssey as shown below. If the space station is 1800 m in diameter, what angular velocity (in radians per second) would produce an artificial gravity similar to that on Earth inside the outer wall of the station?
