Question

Sebuah benda melakukan gerak melingkar dengan frekuensi f. Jika frekuensi dijadikan 3f, berapakah perbandingan besar percepatan sentripetalnya?

Answer 1

Verified answer

Diket :
r = r
f1 = f
f2 = 3f

Jawab :
as = W^2 x r
as = (2phiF)^2 x r
as = (2phi.f)^2 x r
as1 = 4phi^2.f^2.r

as = W^2 x r
as = (2phiF)^2 x r
as = (2phi.3F)^2 x r
as2= 4phi^2.9F^2.t

Perbandingan :

as1 = as2
4phi^2.f^2.r = 4phi^2.9f^2.r
f^2 = 9f^2
1 = 9

Perbandingan As1 dan As2 adalah 1 : 9
