Answer:
The angular frequency of the ball is 2.173 rad/s.
Explanation:
Given;
mass of the ball, m = 1.8 kg
spring constant, k = 8.5 N/m
maximum displacement of the ball, A = 13 cm = 0.13 m
The angular frequency of the ball is calculated as;
[tex]\omega = \sqrt{\frac{k}{m} } \\\\\omega = \sqrt{\frac{8.5}{1.8}} \\\\\omega = 2.173 \ rad/s[/tex]
Therefore, the angular frequency of the ball is 2.173 rad/s.
