AI Thread Summary
An object with a mass of 0.5 kg is thrown upward at an initial speed of 8 m/s, resulting in a total flight time of 3 seconds. The discussion revolves around calculating the height from which the object was thrown, with participants clarifying the problem's parameters. There is some confusion about the nature of the flight and impact, leading to lighthearted comments. The conversation highlights the need for clear problem-solving approaches in physics, especially for those unfamiliar with the subject. Overall, the thread emphasizes the importance of understanding basic physics concepts for effective tutoring.

How do you solve this problem?

An object of mass 0.5 kg is thrown straight upward with an initial speed of 8 m/s. Its total flight time - from release to impact - is 3s. From what height was the object thrown? (Ignore effects due to the air.)


I am not a physics student. I am a virologist who is trying to learn general physics for tutoring purposes. Just thought this would be a good place to post. Thanks!

I think you're looking for the homework help forums.
 
Yes I can solve it but this sounds like homework so what have you tried so far?
 
Sorry, guys, I just read the post about homework. I will post there instead.
 
i'm confused... so the object was thrown upward, flew for 3 seconds and then hit something ?

Yes … it hit the physics student who threw it … on the head! :biggrin:
 

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...
