Question 1186665: 4. A 40.0 kg mass hung from a spring stretches the spring 87.0 cm. (a) find the spring constant. The mass is pulled 20.0sm down from equilibrium and released. (b) what is the force exerted by the spring on the 40.0 kg mass just before its release? (c) what is the frequency of the motion?
5. An object on a spring whose constant is 30 N/m oscillates at a frequency of 10 Hz. What is the mass of the object?
6. A 4.0 kg block is hung from a spring and extends the spring 16 cm from its un-stretched position. (a) find the spring constant. (b) the block is removed and a 0.50 kg object is hung from the same spring. If the spring is then stretched and released, what is its period of motion?

NEVER submit more than one problem per post.

It is the RULE and the POLICY of this forum.


It is written in this page

https://www.algebra.com/tutors/students/ask.mpl?action=ask_question&topic=Equations&return_url=http://www.algebra.com/algebra/homework/equations/

from which you post your problems.


It is assumed that you read these rules before posting.

It is also assumed that you do understand what is written in that page and follow the rules.


        This rule is established for benefits of visitors  (to avoid mess in responses).

        Those who violate them,  work against their own interests.
