I haven't seen any language in the loan/grant documents that stipulates it is only to be used for specific majors. It's pretty much for any major.

So that can also apply to what field they want to do in physics, which makes it socially/morally acceptable to use aid to explore as many classes as possible in physics. Thank you very much Choppy and analogdesign for answering my questions.

Sorry, my bad. I'm a transfer student, so I'm supposed to finish in two years, but I've heard you can stay for three with guaranteed financial aid. For remaining a physics major, I am waiting to see if I'll actually enjoy and excel in upper division courses. If I don't do well, I'm pretty much...

I have transferred from community college, so I am supposed to finish in two years. However, some people can petition to stay for three years I believe. I'm an undergraduate physics major thinking of staying for three years, where there is guaranteed financial aid during that time frame, to take...

ohhhhh gosh finally got it on my calculator >.<Thanks for helping! :)

so v^2=37.5^2+2(-9.8)(-156.25m) v=40.7m/s ..:( still didn't give me -66.8 m/s positive direction is up

Homework Statement A physics student launches a model rocket from the ground at t=0. The rocket ascends with a constant vertical acceleration of a1= 2.5m/s^2 until T1= 5.0s, when the acceleration increases to a2= 5.0m/s^2 until T2= 10.0s. When t>T2, the engine shuts down entirely. (b) What is...

Homework Statement A baseball is seen to pass upward by a window 23m above the street with a vertical speed of 14m/s. If the ball was thrown from the street, (a) what was the initial speed, (b) what altitude does it reach, (c) when was it thrown, and (d) when does it reach the street again...

Homework Statement a boat that can travel at 12.5 m/s on a lake goes 10.6 m/s when going straight up river (with respect to land) if the boat turns and heads (points) 22 degrees upstream from straight across the river. what is the boat's resultant velocity Homework Equations I don't...

Yush! It worked! Thanks a bunch!

Homework Statement When an object is located very far away from a convex mirror, the image of the object is 18 cm behind the mirror. Using a ray diagram drawn to scale determine where the image is located when the object is placed 9.0 cm in front of this mirror. Note that the mirror must be...

What should I put in for h and k? Thank you, CompuChip!

it is not moving, x=0?

Homework Statement A 3.2-kg block is hanging stationary from the end of a vertical spring that is attached to the ceiling. The elastic potential energy of this spring/mass system is 1.8J. What is the elastic potential energy of the system when the 3.2-kg block is replaced by a 5.0-kg block...

omega!=2pi/T 7.54*10^4= 2pi*f f=12006 12006*2.5s= 30016 times? It says to use three significant digits from start to finish. How do I do that? Sorry, I haven't learned this! Thanks danago!
