sebuah benda berputar 600 putaran permenit . jika jari jari lingkaran 50 cm maka percepatan sentripental benda tersebut adalah

Diket :
w = 600rpm = 600x2phi/60 = 20phi rad/s
r = 50 cm = 0,5 m

Jawab :
as = w^2.r
as = (20phi)^2 x 0,5
as = 400phi^2 x 0,5
as = 200 phi^2
as = 200 x 3,14 x 3,14
as = 1971,92 m/s
