During his training as a Canadian astronaut, David Saint-Jacques was submitted to accelerations in a horizontal "centrifuge". Such a device is considered to have a radius of 5.0 m and can generate a centripetal acceleration equivalent to 7 times the acceleration gravitational average on Earth.
At how many turn per minute should the rotation be made to have such an acceleration?
a = 7 g = 7*9.8 = 68.6 m/s^2
r w^2 = 68.6
5* w^2 = 68.6
w = 3.704 rad/s
w = 3.704* 60/(2* pi)
w = 35.39 turns/ min
==========
Comment in case any doubt, will reply for sure. Goodluck

Steve was subjected to accelerations in a horizontal "centrifuge". It is considered that such a device has a radius of 5.0 m and can generate a centripetal acceleration equivalent to 7 times the average gravitational acceleration on Earth. a) For this maximum acceleration, what is the modulus of the astronaut's speed along the circular path? b) At how many revolutions per minute should the rotation occur to achieve such acceleration? c) What is the period of this rotation?
A 75.0 kg astronaut is training for accelerations that he will experience upon reentry. He is placed in a centrifuge (r = 20.0 m) and spun at a constant angular velocity of 15.0 rpm (revolutions per minute). He is then slowed and brought to a stop in 2.0 minutes. a. Find the magnitude and direction of the centripetal acceleration and force when he is spinning at constant angular velocity. b. How many g’s is the astronaut experiencing when moving at...
As their booster rockets separate, Space Shuttle astronauts typically feel accelerations up to 3g, where g = 9.80 m/s2. In their training, astronauts ride in a device where they experience such an acceleration as a centripetal acceleration. Specifically, the astronaut is fastened securely at the end of a mechanical arm, which then turns at constant speed in a horizontal circle. Determine the rotation rate, in revolutions per second, required to give an astronaut a centripetal acceleration of 2.97g while in...
How can we assess whether a project is a success or a failure? This case presents two phases of a large business transformation project involving the implementation of an ERP system with the aim of creating an integrated company. The case illustrates some of the challenges associated with integration. It also presents the obstacles facing companies that undertake projects involving large information technology projects.
