i got A and B...but how would i manage part c? im not seein anyway to cancel out the mass...

I think people on these boards are more familiar with teh ViVfdat method (same sort of thing...) again same sort of concept as ur last problem...no initial y velocity...no x acceleration...then just set up a system with the values...knowing that acceleration in y direction is g and then...

but I am confused as if anything else would be needed...liek that blank befor e the W...would i need to expand any further or would i just keep it Fnbottom - Fntop = xW b would just be v^2/r = g? and then t = 2pir/v and c would be Fnb = mv^2/r + mg...but how would i eliminate m?

I'm on the right track, but I'm stuck here... The radius of a Ferris wheel is 5 m and it makes one rev in 10 sec a Find the difference b/w the apparent weight of a passenger at the highest and lowest points, expressed as a fraction of his weight, W b What would the time for one rev be...

well i got part a...instead of a quadratic i just took the root of everything...now part b seems to be confusing me...g = GMe/R^2?

hmm I am still gettin two #'s that don't make sense for the first one... okay so acc = acc v^2/r = GM/4r^2<<?

for the first one i got 431305921.4 m/ 337924847.8 m arent those both between the Earth and the moon? i don't get which one would be the correct answer in this case... and for the 2nd question...would it be m^2 because u have would have the masses of each being equal? so v^2/r =...

Algebraically I got R^2 - 2Rx + x^2 = Mm/Me x^2 is this correct? but I am getting two positive values for the quadratic? and for the 2nd one... v^2/r = G2M/ R^2 ? where R is 2r?

A couple of questions that I am struggling with again...that I really need to figure out ASAP On the way to the Moon the Apollo astronauts reached a point where the Moon's gravitational pull became stronger than the Earth's. (a) Determine the distance of this point from the center of the...

okay i understand the acceleration part...a = g/μ...was just a little confused because the normal force had no force acting in the opposite direction...but how would it look to an observer? wouldn't it just remain stationary and look like it was a part of the cart?

Umm...I having trouble with the concept of acceleration and friction i guess...or something... What acceleration must a cart have in order that the block A will not fall the coefficient of static friction between the block and the cart is μ , how would the behavior of the blokc be described...

I understand the majority of introductory kinematics...except for these couple of questions... Question #1 A student falls from a 300 M building and starts free fall, five seconds later, superman arrives and dives off the roof to save the student... a) what must be superman's initial...

thank you very much, electrostatics really isn't my strong suit...meaning there will probably more to come soon...

okay i just found this forum and i think now would be a good time to utilize it... okay first q... 1) Two lightbulbs, one rated 30 W at 120 V and another rated 40 W at 120 V, are arranged in two different circuits, if connected in series to a 120 V source, what is the resistance and...

well i found the error of my ways... the whole +/- 1% threw me off... i get the right answer if i multiply by the magnetic field by 1% and then re-plug everything in... hopefully this helps someone in the future...
