SUMMARY

The discussion focuses on calculating the maximum revolutions per second for a spaceman undergoing circular motion with a radius of 5 meters and an acceleration limit of 9g. The relevant formulas for centripetal acceleration are provided: a = mv²/r and a = mr²ω. Given that the acceleration due to gravity (g) is approximated as 10 m/s², participants are encouraged to apply these equations to derive the maximum permissible revolutions.

PREREQUISITES
  • Centripetal acceleration concepts
  • Understanding of angular velocity (ω)
  • Basic physics of rotational motion
  • Familiarity with the formula a = mv²/r
NEXT STEPS
  • Calculate maximum revolutions per second using a = mv²/r
  • Explore the relationship between linear velocity and angular velocity
  • Investigate the effects of varying radius on centripetal acceleration
  • Study real-world applications of centripetal acceleration in aerospace engineering
USEFUL FOR

Physics students, aerospace engineers, and anyone interested in the dynamics of circular motion and acceleration limits in training scenarios.

Circular Motion

A spaceman is in training is rotated in a seat at the end of a horizontal rotating are of length 5m. If he can withstand accelerations up to 9g, what is the maximum number of revelutions per second permissable? The acceleration of free fall (g) may be taken as 10m/s.

i would give what i have tried but i have no idea what equation to use?
any ideas?

Hi ben2010! :wink:

Use the formula for centripetal acceleration …

a = mv2/r = mr2ω :smile:
