wooooooo

Answer 27

and he doesn't really care about sig figs right now but thanks c: I try getting them anyways for practice. I'll look and fix it

Answer 28

1... 50m/s? that drops it to 1 sig fig..

2...4.0m/s^2?

Answer 29

I'll check the sf at the end.
For 3. You can use only one formula to find the answer.
\[x _{f}=x _{i}+v _{_{i}}t+\frac{ 1 }{ 2 }at^2\]

Answer 30

I haven't seen that formula before O.O

Answer 31

We only have 4

Answer 32

nevermind.. yes I have XD

Answer 33

lol

Answer 34

but I still got the right answer, right?

Answer 35

Same goes for 5.

4 is correct.

Answer 36

Wait nvm you would still need 2. Your way is faster for 5.

Answer 37

haha thanks xp

Answer 38

did I get 3 right?

Answer 39

You're not stuck on 6 right?
You are just taking a break?

Answer 40

Yes.

Answer 41

Plug in the values to the equation I gave you and it would still be the same with by just using 1 formula.

Answer 42

I'm on 8 right now lol

Answer 43

Nice!

Answer 44

I got 1.5m for 6 and -0.13m/s^2

Answer 45

for 7

Answer 46

well I got the final velocity to be 9.6m/s

then I used the formula \(v^2=v_0^2+2a(x-x_0)\)

Answer 47

9.6^2=92.16m
92.16m=0+2(3.2m/s^2)(d)
92.16m/6.4m/s^2=14.4m or 14m when rounded to sf.

Answer 48

You can tell your answer is wrong by reading the problem and thinking like this :

Answer 49

Hmm, if a car accelerate for 3.2m/s^2 for 3 sec straight, wouldn't the distance be more than like around 5m?

Answer 50

It speeds up by 3.2m/s^2 every second

Answer 51

OMG I SEE MY MISTAKE

Answer 52

I didn't square 9.6 lol

Answer 53

I dunno if I got 8 correct... i got 25m/s after I rounded

Answer 54

lol

Answer 55

7 is correct.

Answer 56

Foe 8, I got the same results.

Answer 57

oki yay

Answer 58

I'm starting on 9 now

Answer 59

I got no for 9.. because the final velocity is 5m/s

Answer 60

is that right?

Answer 61

OMG http://prntscr.com/8e69uy

Answer 62

LMAO

Answer 63

For 9, I got no because it would be at 25m/s 0.0

Answer 64

that's what I meant lol

Answer 65

sorry XD I have issues typing the right numbers for some reason XD

Answer 66

Lol, no wonder.

Answer 67

what would I do for 10?

Answer 68

Hint: one formula.

Answer 69

hang on.. I may be able to figure it out

Answer 70

the formula you showed me right..

Answer 71

?

Answer 72

yes

Answer 73

gimme a sec.. everyone is talking

Answer 74

you can't add t and t^2, can you?

Answer 75

OMG I KNOW WHAT TO DO.. I CAN USE THE QUADRATIC FORMULA

Answer 76

wait.. I got both negative answers..but it's time.. @Shalante can you walk me through this?

Answer 77

wait... nevermind xp I graphed it and got 4.. is it 4 seconds?

Answer 78

You would need quadratic, which is a pain.
So the one formula I told you to use was bad.
vf^2=v^i+2ax then vf=vi+at is better.

Answer 79

If you are given everything except time in the formula, then it would be a good idea to use that 1 formula.

Answer 80

ok.. sorry I'm getting stressed

Answer 81

so which one?

Answer 82

ohhh do the two separate ones like I have been?

Answer 83

You got 4 right.
Did you do it using 1 formula or 2?

Answer 84

I graphed the quadratic from the first equation you had me use xp

Answer 85

Either way works but the one formula is annoying since it has a quadratic.

Answer 86

Dont do that next time.
I messed up also because I hinted you to do it in 1 formula instead of 2.

Answer 87

vf^2=v^i+2ax then vf=vi+at

Answer 88

bc I tried the quadratic formula but messed up then I just graphed it XD

Answer 89

OMG I FOUND MY MISTAKE AND GOT IT WITH THE QUADRATIC FORMULA :D

Answer 90

Ok next question.

Answer 91

ok.. idk what to do here

Answer 92

Are you focusing better right now?
Because this question is similar to the ones you done.

Answer 93

no I'm not tbh

Answer 94

I GOT IT
