The first part I can answer. However, the answer to the second one differs from the one in the answer sheet. 1) The rocket first travels gaining speed (a=40m/s^2) and then after the fuel burns loses speed due to g=9.8 m/s^2. Thus, Hmax= h1 (traveled with a=40) + h2 (traveled with -a=g=9.8)...

Alright, thanks. I figured out what I asked for, however it is interesting to know that breaking in a line compared to braking in an angle does not drastically affect the braking distance / time. Thanks

My guess is that distance Car A needs to travel until it stops is longer than car B (not by much), and so it the time. I also posted this question to reddit, if you want to check it out : I got the answer, but unsure of it's legitimacy.

I have no experience with Arduinos, microcontrollers or electricity at all. I just made 4W speaker and that's literally it, so it would be a challenge for me as well. I like the idea of it tho. I will talk with the teacher and think about it.

This looks interesting Do you mean something like this just more advanced? Also other thing is that my project needs to have at least 10 pages of theory stuff, so will I have enough INFO / won't this be too hard to make for a 9th grader? Thanks for helping me out, if you or anyone else have...

Homework Statement Hello, here in Europe we have such thing as 9th grade yearly Science project. Basically students divide into either physics, chemistry or biology, so I chose physics since it is most interesting. But here I faced a problem. We need to choose topic for your project and I have...

Thanks for your help. I definitely learned a lot.

+T2-T1=+w +T2=+T1+w +T2-w=+T1 T2-Q:mc=T1 I hope i got it right this time, did I?

T2-T1=Q:mc I can't just move Q:mc freely becouse of division between Q and mc and because of multiplication between m and c. E.g ρ=m:V Makes m=ρV So I can't use my math trick Sorry if I got your question wrong

T2-T1=Q:mc T2=Q:mc+T1 T2:Q*mc=T1 T1=T2:Q*mc Did I get it right this time?

I got Delta T=Q:mc Delta T=T2-T1 so formula is T2-T1=Q:mc and I just used simple math trick that if you change sides, it just changes from + to - and - to + e.g x=+4 meaning x-4=0 So from T2-T1=Q:mc formula I got these two: T1=Q:mc-T2 T2=Q:mc+T1

Homework Statement [/B] I just got this formula from class : Q=mc(T2-T1) and got task to make 2 more formulas from this oneHomework Equations How do I make these formulas : T1=? and T2=? The Attempt at a Solution T2=Q:mc-T1 T1=-T1 T1=Q:mc+T2 Thanks for help
