I've decided to submit the answers I have to my teacher. I'm not fully confident in the validity of the answers, but with the deadline rapidly approaching, I figure its best to just submit the answer and ask for clarification. If needed, I can update the thread with his response later on. Thanks...

Ahh, you're right, I forgot to square tangential speed. Thanks for the catch :). I drew a free body diagram and ended up with a centripetal force towards the Earth (the gravitational pull, which, if we are using 9.8m/s2 as our acceleration due to gravity, is equal to 19.6 Newtons) and an...

Ahh, yes, I didn't clarify in my previous posts; there is a chart attached to my homework detailing the thrust of a single D11-5 engine that states that the thrust phase is 1.7 seconds long. The 5 second period is the coasting phase before the parachute deploys, not the period in which thrust is...

It's part 2 of a two-part question, I've attached the first part in its entirety below (bold text). He usually doesn't provide much irrelevant information, but I suppose there is a possibility that it could be in this case. 2) Suppose a person decides to make a low-budget satellite by...

Well, no, but I've been taking classes (including a full year of biology and chemistry) from this guy for several years now, and he's never given us homework beyond what he's taught in the classes.

You're right, allow me to clarify. I meant that in the course of our physics lessons, we haven't covered universal gravitation, so I'm assuming this is something that can be solved using our existing knowledge of angular kinematics and rotational motion. Universal gravitation is something that...

So, I'm working on my semester finals for my high school physics class, and I've run across a problem that has me stumped. I've included the pertinent material below. Homework Statement A rocket with a mass of 2kg and traveling at 14,008.34 meters/second loses 10% of its velocity as finishes...

Hey all, I thought I'd take a second to introduce myself here and just say hi to everyone on the forums. I'm currently a high school student looking at a career in astrophysics, so I figured this would be a good place to hang around for help with problems/clarifying some facts. Looking forward...
