Question 2 of 20 -/ 5 View Policies Current Attempt in Progress The National Aeronautics and Space Administration (NASA) studies the physiological effects of large accelerations on astronauts. Some of these studies use a machine known as a centrifuge. This machine consists of along arm. to one end of which is attached a chamber in which the astronaut sits. The other end of the arm is connected to an axis about which the arm and chamber can be rotated.The astronaut moves on a circular path. much like a model airplane ying in a circle on a guideline. The chamber is located 16.0 m from the center of the circle. At what speed must the chamber move so that an astronaut is subjected to 5.2?r times the acceleration due to gravity?

There is a particle of mass me attached to the center of the rod and a particle of mass ing attached to the outer end of the rod. The inner section of the rod sustains a tension that is 2 times as great as the tension that the outer section sustains. Find the ratio my/my.

On this surface the cars race in circles that are parallel to the ground. For a speed of 36.4 my's, at what value of the distance d should a driver locate his car if he wishes to stay on a circular path without depending on friction? 40.07 40.0 Number i Units
