PERCEPATAN PADA MOMEN INERSIA
Perbandingan Percepatan Momen Inersia pada Bola Pejal, Bola Berongga, Silinder Pejal, dan Cincin Diasumsikan \[\theta = 90^\circ, \quad g = 10 \, \text{m/s}^2\] BOLA PEJAL \[a = \frac{F}{\left(\frac{I}{r^2} + m\right)} = \frac{F}{\left(\frac{\frac{2}{5}mr^2}{r^2} + m\right)} = \frac{m g \sin \theta}{\frac{2}{5}m + m} = \frac{g \sin \theta}{\frac{7}{5}} = \frac{5 g \sin(90^\circ)}{7} = \frac{5 \cdot 10 \cdot 1}{7} = 7.14 \, \text{m/s}^2\] BOLA BERONGGA \[a = \frac{F}{\left(\frac{I}{r^2} + m\right)} = \frac{F}{\left(\frac{\frac{2}{3}mr^2}{r^2} + m\right)} = \frac{m g \sin \theta}{\frac{2}{3}m + m} = \frac{g \sin \theta}{\frac{5}{3}} = \frac{3 g\sin(90^\circ)}{5} = \frac{3 \cdot 10 \cdot 1}{5} = 6 \, \text{m/s}^2\] CINCIN \[a = \frac{F}{\left(\frac{I}{r^2} + m\right)} = \frac{F}{\left(\frac{mr^2}{r^2} + m\right)} = \frac{m g \sin \theta}{m + m} = \frac{g \sin \theta}{2} = \frac{g \sin(90^\circ)}{2} = \frac{10 \cdot 1}{2} = 5 \, \text{m/s}^2\] SILINDER PEJAL \[a = \frac{F}{\left(\frac...
