Maximum Height Reached by Block on Spring

AI Thread Summary
The discussion focuses on calculating the maximum height a block reaches after being released from a compressed spring. The initial energy stored in the spring is calculated as 22.4874 J, while the weight of the block is determined to be 2.45 N. The work-energy principle is applied to find the distance the block travels, resulting in a calculated height of 9.178 m. However, it is noted that the final height must account for the spring's compression, requiring a subtraction of the compression distance from the total height. The correct approach emphasizes the need to adjust for the initial compression of the spring to find the actual height above the release point.

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.
 

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
