Maximum Height Reached by Block on Spring

Click For Summary

Homework Help Overview

The problem involves a block placed on a vertical spring, where the spring is compressed and then released. The objective is to determine the maximum height the block reaches after leaving the spring. The subject area includes concepts of energy conservation and mechanics.

Discussion Character

  • Exploratory, Conceptual clarification, Mathematical reasoning

Approaches and Questions Raised

  • Participants discuss energy calculations related to the spring and the block's weight. There is an attempt to equate the energy stored in the spring to the work done against gravity. Questions arise about the interpretation of the maximum height and the necessary adjustments for the spring's compression.

Discussion Status

Some participants are exploring the energy conservation approach, while others are questioning the assumptions made in the calculations. There is a recognition of the need to adjust for the spring's compression in determining the height above the release point. No explicit consensus has been reached regarding the correct approach.

Contextual Notes

Participants note that the problem specifically asks for the height above the point of release, which introduces a consideration of the spring's compression in the final calculations.

A block of mass 0.250 kg is placed on top of a light vertical spring of constant k = 5200 N/m and is pushed downward so that the spring is compressed 0.093 m. After the block is released, it travels upward and then leaves the spring. To what maximum height above the point of release does it rise?

my attempt:
energy in spring = (.5)5200(.093)^2=22.4874J
Weight of block = .250x9.8=2.45N
W=fxs
22.4874=2.45xs
s=9.178

What am i doing wrong?
 
Physics news on Phys.org
use the Energy formula involving initial and final energy.
 
what is it?
 
What makes you think you are doing these wrong? I got the same answer. Same thing with your centrifugal force problem. They both look good to me.
 
it was wrong because it asks how high does the block go above the spring so i had do minus the length of compression of the spring from the final answer.
