Ahorizontal spring oscillator consists of a mass attached to a spring of constant 712 n/m. there is no friction. what mass (kg) should be attached for the oscillator to oscillate with a period of 0.47 seconds?

3.99 kg

Explanation:

The period of a harmonic oscillator is given by:

where

m is the mass attached to the spring

k is the spring constant

In this problem, we know:

k = 712 N/m

T = 0.47 s

Therefore, we can re-arrange the equation to find the mass that should be attached to the oscillator:

think its the third option
