Homework Help Overview

The discussion revolves around calculating the amplitude and period of a block attached to a spring in simple harmonic motion. The original poster presents two specific questions related to the motion of a block released from rest, involving the spring constant and mass.

Discussion Character

  • Exploratory, Assumption checking, Problem interpretation

Approaches and Questions Raised

  • The original poster attempts to use relevant equations but expresses uncertainty about missing information. Another participant questions the conditions under which the net force on the block is zero and prompts a description of the block's motion over one complete period.

Discussion Status

The discussion is ongoing, with participants exploring different aspects of the problem. There is a focus on understanding the relationships between the variables involved in simple harmonic motion, but no consensus or resolution has been reached yet.

Contextual Notes

The original poster indicates a lack of clarity on the equations needed to solve the problem, and there is a mention of an image that may provide additional context. The specific values for the amplitude and time are not provided, leaving some assumptions open for discussion.

Homework Statement


How do I solve the 2 questions below?:

Questions 23 24
A 0.l kilogram block is attached to an initially unstretched spring of force constant k = 40 Newtons per meter as shown above. The block is released from rest at time t = 0. (the image is attached below).

23. What is the amplitude of the resulting simple harmonic motion of the block?
(A) m (B) (C) (D) (E) 1m

24. At what time after release will the block first return to its initial position?
(A) (B) (C) (D) (E)

Homework Equations



w^2= k/m
x = Asin(wt)
F=kx
dunno wat else??

The Attempt at a Solution



I tried plugging in those 3 equations together and manipulating equations. couldn't get anything though. Someone please help. I think I'm missing an important equation.

can someone help pl0x
 


How far does the spring stretch when the net force on the block is zero? i.e. when k·|x-x0|=mg .

Describe the motion of the block (in words) over one complete period.
