~ jika 2 roda, dihubungkan dengan tali. Kecepatan sudut nya sama walaupun jari" nya berbeda.
5). Gerak melingkar berubah beraturan
~ alfa = ∆omega/∆t. > ∆v/∆t
alfa = (40-20)/5
alfa = 20/5 ~ 4rad/s'2
~ vt'2 = vo'2 + 2.a.s
~ omega t'2 = omega o'2 + 2. alfa. theta
40'2 = 20'2 + 2. 4. theta
1600 = 400 + 8theta
8theta = 1200
theta = 1200/8 ~ theta = 150 radian.
