  1. Ffr = µsFn
  2. Ffr = 0.4 * m * 9.8 m/s^2
  3. Ffr = 0.4 * 1kg * 9.8 m/s^2
  4.  
  5.  
  6. Ffr / Fn = µs
  7. Ffr / Fn = 0.4
  8.  
  9. F = m2 * a
  10. ||Ffr|| = m2 * 9.8 m/s^2
  11. (m2 * 9.8 m/s^2) / (m1 * 9.8 m/s^2) = 0.4
  12. m2 / m1 = 0.4
  13.  
  14. m2 = m1 * 0.4
  15.  
  16. Since d2 = d1 (density)...
  17.  
  18. l2 = l1 * 0.4
  19. l2 = 1m * 0.4
  20. l2 = 0.4m
