- Semi-trailer trucks have an odometer on one hub of a trailer wheel. The hub is weighted so that it does not rotate, but it contains gears to count the number of wheel revolutions-it then calculates the distance traveled. If the wheel has a 1.11 m diameter and goes through 150,000 rotations, how many kilometers should the odometer read? (Enter a number.) kmIn an amusement park ride called The Roundup, passengers stand inside a 19.0 m -diameter rotating ring. After the ring has acquired sufficient speed, it tilts into a vertical plane, as shown in ( Figure 1).

How long does it take to make 8 revolutions?A dirt bike is traveling at a constant speed v when it happens upon a circular hill of radius r = 410 m. The driver and dirt bike together have mass m = 136 kg. a.) What speed in m/s does the dirt bike have if the driver feels weightlessness (i.e., has an apparent weight of zero) at the top of the hill? b.) If the driver is traveling at the speed above and happens upon a hill with a radiues 2r, what is the apparent weight of both the driver and the dirt bike in Newtons at the top of the hill?1) F. = N+ mg %3D A skier goes over a small round hill with radius R.

- Chapter 5 Problem 8: BIO Ultracentrifuge You are working in a biology lab and learning to use a new ultracentrifuge for blood tests. The specifications for the centrifuge say that a red blood cell rotating in the ultracentrifuge moves at and has a radial acceleration of 150,000 g’s (that is, 150,000 times ). The radius of the centrifuge is 0.15 m. You wonder if this claim is correct. Support your answer with a calculation.Question 194. We are planning a human exploration mission to Mars. We will first place our spacecraft into a circular around Mars and then send down a lander. a) If we want the spacecraft to orbit at an altitude of 170 km above the Martian surface, what will the velocity and orbital period of the spacecraft? b) When we land astronauts on the surface of Mars, what acceleration due to gravity in terms of g's (i.e. as a fraction of the Earth's gravitational acceleration) will the astronauts experience? You are permitted to use an online resource (e.g. Google) to find the necessary information about Mars that you might need in solving this problem.
