A ball whose mass is 1.8 kg is suspended from a spring whose stiffness is 8.5 N/m. The ball oscillates up and down with an amplitude of 13 cm. (a) What is the angular frequency

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;

Therefore, the angular frequency of the ball is 2.173 rad/s.
