Dik: D = 56 m ---> r = 56/2 = 28 m v = 10 m/s
Dit: As = ..... m/s²
Jawab: As = v²/r As = 10²/28 As = 100/28 As = 3,57 m/s² atau disederhanakan As = 4 m/s² (Jawaban Fail,)
kemungkinan 56 itu bukan diameternya, tapi jari-jari. Kalau 56 jari-jari, maka: As = 100/56 As = 1,78 m/s² atau disederhanakan As = 2 m/s²
D = 56 m ---> r = 56/2 = 28 m
v = 10 m/s
Dit:
As = ..... m/s²
Jawab:
As = v²/r
As = 10²/28
As = 100/28
As = 3,57 m/s²
atau disederhanakan
As = 4 m/s² (Jawaban Fail,)
kemungkinan 56 itu bukan diameternya, tapi jari-jari. Kalau 56 jari-jari, maka:
As = 100/56
As = 1,78 m/s²
atau disederhanakan
As = 2 m/s²
