Suatu titik melakukan gerak melingkar beraturan sehingga tiap menit membuat 300 putaran. Jika jari jari lintasan 4 cm,percepatan sentripetal adalah

Diket :
F = 300 rpm
r = 4 cm = 0,04 m

Jawab :
300 rpm x 2π/60 = 10π rad/s

as = w^2.r
as = (10π)^2.0,04
as = 100π^2 x 0,04
as = 4(3,14)^2
as = 39,44 m/s^2

Maaf jika ada kesalahan :)
