The centripetal force on a body depends on m, v and r: F = k,m^av^br^c. Then

  1. a = 1, b = 2, c = 1
  2. a = 1, b = 1, c = 1
  3. a = 2, b = 1, c = -1
  4. a = 1, b = 2, c = -1
Answer

D) a = 1, b = 2, c = -1

M: a = 1; T: -b = -2 Rightarrow b = 2; L: b + c = 1 Rightarrow c = -1: F = kmv^2/r. SLO P-11-A-04 · Application
