Answer 2

can u help with this problem

Answer 3

\(\huge \vec a=a_r+a_t\)
\(\huge a_r=-a_c=-\dfrac {v^2} r\)
\(\huge a_t=\dfrac {dv} {dt}\)

Answer 4

i used the first newton law and came out with Nsinpehta= mvsquared/r was that wrong

Answer 5

@vsandrasue why are you writing on @Lethal 's question?

Answer 6

did my x's and my y's with the 1st newton law and the y's i got Ncospetha-mg=0 so (N=mg/cospetha). oh sorry let me find yours.

Answer 7

Why are you typing here though?

Answer 8

Okay. Sorry for just getting onto this now. But how do you get At?

Answer 9

I got Ar=-(v^2)/r=-(.798^2)/.175= -3.6388

Answer 10

Now just need At

Answer 11

Answer 12

And maybe I did something wrong because I haven't used the .64 s

Answer 13

you don't need the radial...at least not from what i can tell

Answer 14

Okay. So then what do we use for dv/dt

Answer 15

sorry, can't think straight
