Astronauts often undergo special training in which they are subjected to extremely high centripetal accelerations. one device has a radius of 15 m and can accelerate a person at 98 m/s2. what is the speed of the astronaut in this device?

 Speed of astronaut = 38.34 m/s

Explanation:

 Centripetal acceleration is given by the expression, , where v is the velocity and r is the radius.

 Here centripetal acceleration is given, radius is given, we need to find velocity.

 Centripetal acceleration = 98 m/s²

 Radius = 15 m.

 We have,

Speed of astronaut = 38.34 m/s
