Acceleration for first half of trip... apply newtons second law... net force = m a = - F fr = - (Mu s Fn) were Mu s is coefficent of static friction take the inverse of m onto both sides a = m^-1 -(Mu s Fn) apply Newtons second law in the y direction net force (y direction) = ...

ok Boxes are moved on a converyor blet from where they are filled to the packing station 10m away. The belt is initially stationary and must finish with zero speed. The most rapid transit is accomplished if the belt accerlates for half the distance, then decelerates for teh fi...

I'm trying to prove Kepler's equations the proof is in my book but I don't understand it (T1/T2)^2 = (s1/s2)^3 ok first what allows us to rewrite that formula as so??? (s1^3/T1^2)=(s2^3/T2^2) my book goes about the proof as m1 ((4 pi^2 r1)/T1^2) which I get but the...

QUESTION
oh and also what makes angle three equal to angle to if you extended the lines

QUESTION
what are these opposite angles that you are making reference to sorry it's been a while sense I took geometry

QUESTION
I agree and as you can see I wrote "...Vo^2 dosen't become Vo" not ""...Vo^2 dosen't become V"

QUESTION
I didn't right Vo^2 as V...

Question
ok why are they the same thing???

Physics
no that was it thanks
