Question

Roda yang memiliki jri jari 35 cm dan bergerak dengan kecepatan 540 rpm, percepatan sentripetal pisau blender adalah....m/s

Answer 1

F = 540 rpm = 540/60 = 9 Hz
R = 0,35 m
as = __?

w = 2π f = 18π rad/s

percepatan sentripetal
as = w² R
as = (18π)² • 0,35
as = 113, 4 π² = 1120 m/s² ← jwb
