Aspring has an unstretched length of 14 cm . when an 81 g ball is hung from it, the length increases by 6.0 cm . then the ball is pulled down another 6.0 cm and released. a. what is the spring constant of the spring?
b. what is the period of the oscillation?

To solve this problem we will apply the two concepts mentioned. To find the constant we will apply Hooke's law, and to find the period we will apply the relationship between the mass and the spring constant. Let us begin,

PART A) For this section we will use Hooke's law. In turn, since the force applied is equivalent to weight, we will use Newton's law for which weight is defined as the product between mass and gravity. This weight is equal to the Spring Force.

Here,

k = Spring constant

= Displacement

F = Force, the same as the Weight (mg)

Then we have that

Therefore the spring constant is 13.23N/m

PART B)  To find the period of oscillation, the relationship that allows us to find is given by the following mathematical function,

Here

m = mass

k = Spring constant

Replacing,

Therefore the period of the oscillation is 0.491s

science is a systematic and logical approach to discovering how things in the universe work. true to this definition, science aims for measurable results through testing and analysis. science is based on fact, not opinion or preferences. the process of science is designed to challenge ideas through research.
