A ball whose mass is 13 kg is suspended from a spring whose, Ask an Expert

Academics

A ball whose mass is 1.3 kg is suspended from a spring whose stiffness is 3 N/m. The ball oscillates up and down with an amplitude of 10 cm.

(a) What is the angular frequency?

(b) What is the frequency?

(d) Suppose this apparatus were taken to the Moon, where the strength of the gravitational field is only 1/6 of that on Earth. What would the period be on the Moon? (Consider carefully how the period depends on properties of the system; look at the equation.)
