well thank you for helping me.

does it matter if my final calculation is not the exact answer as the book's. when i had finished solving i got 938.5 instead of 941.

so then my final velocity that i had calculated from the acceleration phase would replace my original initial velocity which as 0.

i'm sorry what do you mean when you said "How much higher does it go against gravity alone?"

Homework Statement a rocket moves upward, starting from rest with an acceleration of +29.2 m/s^2 for 4 s. it runs out of fuel at the end of the 4 s and continues to move upward. how high does it rise? Homework Equations The Attempt at a Solution i tried using the equation...

Homework Statement C1e^2x + C2Xe^2x is what i need to derive. Homework Equations The Attempt at a Solution my teacher got this 2C1e^2x + C2e^2x + 2C2Xe^2x. when i derived i got 2C1e^2x + 2C2e^2x. can someone tell me which is correct and if i am wrong, what should be done to...

thanks a lot now i know the book has a few typos because i have encountered a few

so is my matrix correct and there is a typo in the book?

i need help with a linear equation problem. I started the problem and after a few steps i checked the problem in the solution manual and there seem to be a typo in the text so i wanted to have someone check my work if i was doing it correctly. if i made a mistake can someone please correct me...

ok thanks a lot my other question is what if the rotating object was rolling down a incline and it started at rest. would the velocity be the velocity of center mass of the object that is being rolled.

i used the formula for KE rotation KE=(1/2)Iw^2 and i translated it to (1/2) v^2/r^2, but i wanted to know what does the v in the equation stand for. is it initial velocity or velocity of center of mass. if its is the velocity of center of mass can u tell me how to solve for it

ok thanks alot. i don't like math that much and i am having problems grasping the concepts. However i do like working on computers and I'm pretty good with tech work and networking. any suggestions on what i should go into?

ok thanks alot. also i wanted to know under what category would network administration fall under.

my major as of now is computer engineering. i have taken calculus 1 and currently enrolled in calculus 2. i wanted to know how much of calculus will be used on the job later on because I am struggling in math.

Homework Statement can some explain it to me, how to solve? also can how to find instantaneous velocity? Homework Equations The Attempt at a Solution
