v = 15 km/jam
r = 15 m
dit : T ?
dijawab :
V = (15x1000)/3.600
= 15.000/3.600
= 4,167 m/s
V = 2xπ x f x R
4,167 = 2x3,14 x f x 15
4,167 = 94,2 x f
f = 4,167/94,2
f = 0,0442
T = 1/f
= 1/0,0442
= 22,62 s
ω = 2π/T
ω= v/R
v/R = 2π/T
T = 2πR / v ---> v = 16 km/jam
= 16.000/ 3600 m/s
= 160/36 m/s
= 40/9 m/s
= 2.(3,14).15 / (40/9)
= 21,2
