SUMMARY

The discussion centers around calculating the initial y-coordinate of the center of gravity (CG) for a flat dance floor measuring 17m by 15m with a mass of 1100 kg, along with three dance couples each weighing 100 kg. The relevant equation for determining the center of mass is provided as ycm = (m1y1 + m2y2 + m3y3) / (m1 + m2 + m3). Participants are encouraged to apply this equation to find the solution and share their progress for further assistance.

PREREQUISITES
  • Understanding of center of mass calculations
  • Familiarity with basic physics concepts, specifically inertia
  • Knowledge of coordinate systems in physics
  • Ability to perform arithmetic operations with masses and coordinates
NEXT STEPS
  • Review the concept of center of mass in physics
  • Practice problems involving multiple masses and their coordinates
  • Explore the implications of inertia in dynamic systems
  • Learn about coordinate transformations in physics
USEFUL FOR

Students studying physics, particularly those focusing on mechanics and center of mass calculations, as well as educators looking for examples of practical applications of these concepts.

Homework Statement



Given: A flat dance floor of dimensions lx = 17mbyly =15mandhasamassofM = 1100 kg. Use the bottom left corner of the dance floor as the origin. Three dance couples, each of mass m = 100 kg start in the top left, top right, and bottom left corners.
What is the initial y coordinate of the cen- ter of gravity of the dance floor and three couples?
Answer in units of m

Homework Equations



xcm: m1x1 + m2x2/m1+m2

The Attempt at a Solution


I am so lost any help would be appreciated! Thanks

Hello Krobinson2851

Why don't you just apply the equation you have written down (and the equivalent one for yCM).
If you get stuck, show us what you've done.
