Homework Statement
Two cars leave the same point at the same time, each traveling at the same constant speed of 89.0 km/h and each having the same mass. However, the first car drives directly east, while the second car heads directly south. At what speed (the magnitude of the velocity) is the...
I'm just about to finish first year Linear Algebra tomorrow morning (that's my final), and all I can say is it truly does not compare to high-school maths at all. High-school was based on, "here's an equation, here's some value, solve for x", university level maths are more like, "here are some...
No, they're about understanding the concepts; which is what I was trying to say, but you need repeat something in order to get it in your memory, once it's there it's easier to understand. There's many ways to go about understanding something, I was expressing my way of doing it.
And that's...
Being a Neuroscience major, it is looking as though your studying habits are not working well enough to keep basic concepts in your long term memory - you should look into study intervals (1 hour on, 15 minutes off). Also, look over your notes 1 hour after your lectures are finished; this...
You don't really need the -signs.
As for the answers, generally speaking, tension is always greater at the bottom of a rotation (I think) due to gravitational potential energy being converted into kinetic energy - judging from this, I would say your answers are right.
As stated, it's 1:00am :bugeye:
Thanks for pointing that out, any idea where I can start to look for the correct equation? I looked at continuity (as suggested), but I am getting a massive amount of time for that.
Edit: I think I figured it out, it was entirely conversions that threw me off...
I fixed up the silly mistakes, it is 1:00am and I've been reviewing for nearly 14 hours now. I just need help finding the correct formulas for solving this problem.
I am aware I have some major mistakes, which is why I posted it. I need help getting started, I only posted what I had to show I made an attempt.
Edit: Oh I see what you are talking about, yes. This is rather embarrassing. Never trust a friend with conversions...
Homework Statement
A garden hose is used to fill a large metal container which can hold 24.0 L of liquid. If the radius of the garden hose's nozzle is 1.2 cm, and the speed of the water at this point is 272.0 cm/s, how long (in seconds) would it take to fill the container with water, assuming...
