Amass m at the end of a spring vibrates with a frequency
of0.88 hz. when an additional 680-g mass is added to m, the
frequencyis 0.60 hz. what is the value of m?

m = 0.59 kg.

Explanation:

First, we need to find the relation between the frequency and mass on a spring.

The Hooke's law states that

And Newton's Second Law also states that

Combining two equations yields

The term that determines the proportionality between acceleration and position is defined as angular frequency, ω.

And given that ω = 2πf

the relation between frequency and mass becomes

.

Let's apply this to the variables in the question.

another example of kinetic energy would be,

kinetic energy   >     moving energy

answer   >   letter choice (c),   a hammer falling off a table.

probably not if net force is zero
