AI Thread Summary
The discussion revolves around a physics problem involving a rocket's motion, specifically its upward acceleration, maximum height, total airtime, and impact speed. The rocket accelerates at 19 m/s² for 30 seconds before the engine shuts off, leading to a phase of free-fall. Participants emphasize the need to show calculations to receive assistance, adhering to forum rules. Additionally, there is a reminder to post homework-related queries in the appropriate section for better support. The conversation highlights the importance of following guidelines for effective problem-solving in academic forums.

Help with a problem!

I've been trying to solve this and cannot seem to be getting the right answer.. please help!

A rocket is fired vertically with an upward acceleration of 19 m/s2. After 30 s, the engine shuts off and the rocket then continues rising (while in free-fall). The rocket eventually stops rising and then falls back to the ground.

a) What is the highest point the rocket reaches?
b) what is the total time the rocket is in the air?
c) what is the speed of the rocket just before it hits the ground?

Thanks!

You are going to have to show some work before we can help you. It's the rules. Also, please post homework problems in the homework help section in the future.
 

Thread 'Need help understanding particle physics and quantum physics'

So I know that electrons are fundamental, there's no 'material' that makes them up, it's like talking about a colour itself rather than a car or a flower. Now protons and neutrons and quarks and whatever other stuff is there fundamentally, I want someone to kind of teach me these, I have a lot of questions that books might not give the answer in the way I understand. Thanks
