AI Thread Summary
The discussion revolves around an urgent request for help with an oscillation problem involving a spring and a block. The block is dropped from a height of 2.8 cm and sticks to the spring, oscillating with an amplitude of 15 cm. The user attempted to apply conservation of energy principles but encountered difficulties in reaching a solution. They emphasize the need for a quick answer, as the assignment is due in two hours. The urgency of the request highlights the pressure students often face with tight deadlines in physics assignments.

Assignement 3; Oscillation problem URGENT

Homework Statement



A spring is standing upright on a table with its bottom end fastened to the table. A block is dropped from a height 2.8cm above the top of the spring. The block sticks to the top end of the spring and then oscillates with an amplitude of 15 cm.

Homework Equations


1/2kx^2 + 1/2mv1^2+ mgh= 1/2KA^2 +1/2mvmax^2

POST ANSWER FIRST THAN EXPLANATION. DUE IN 2 HOURS urgent



The Attempt at a Solution


Tried to use conservation energy and got stuck. Dont need explanation, just an answer, its due at 7pm Est today. I tried to do it on my own but have failed miserably. If someone can do this really fast, post the answer FIRST and than post the explanation you would help me not lose 5% thanks alot.

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 .
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...
