Answer: angular acceleration = [tex]2.86\ rad/sec^{2}[/tex]
Given:
Distance from center of axis = 1.6 m
Time taken to complete one revolution = 4.7 sec
Therefore, we can evaluate the angular acceleration using the following formula:
[tex]\alpha = r\times \omega^{2}[/tex]
[tex]\alpha = r\times (\frac{2\pi}{T})^{2}[/tex]
[tex]\alpha = 1.6\times (\frac{2\times3.14}{4.7})^{2}[/tex]
[tex]\alpha[/tex] = [tex]2.86\ rad/sec^{2}[/tex]
