lol u silly little cheater! :3

Answer 5

cheatah!!! XD

Answer 6

xD

Answer 7

Hmm I think you've got the correct one selected for number 9.
See how you're `differentiating` FIRST?

So the 4 will disappear.
It won't come back after integrating (except that now it's absorbed into the C)

Answer 8

come on guys I have 4 min left plzzz, I answered 9 other questions

Answer 9

For number 10, see how the acceleration function is `constant`.
That means our velocity function should be `linear`, yes?

That should help narrow it down a little bit.

Answer 10

oh its A

Answer 11

wait nevmind

Answer 12

@zepdrix don't help cheaters. Help cheatahs! XDD

Answer 13

linear means its an exponential variable

Answer 14

Integrating we should getttttttt this I think,
\[\Large\bf\sf v(t)\quad=\quad a_o t+v_o\]
That form.
Can you read the information given and fill in the pieces?

Answer 15

I am not cheating, ints only 2 questions

Answer 16

linear means straight line... no square on t... comeon girl -_-

Answer 17

so 10 is A.

Answer 18

hb 3.

Answer 19

3 min

Answer 20

We would leave a +C on the end if they had NOT given us information about the initial velocity.

Answer 21

its b or d

Answer 22

\[\Large\bf\sf v(t)\quad=\quad -9.8t+C\]We can use this information to solve for C,\[\Large\bf\sf v(0)\quad=\quad 60\]

Answer 23

Plug it in! Find your C! :D

Answer 24

2 min how bout 3

Answer 25

3? I don't see a question 3 anywhere :o

Answer 26

Or you mean option 3?

Answer 27

Ok I'm gonna make you figure this one out XD Look back at my notes, you should be able to get it!! :D

Answer 28

\[\Large\bf\sf v(t)\quad=\quad a_o t+v_o\]Ok super hint -_-\[\Large\bf\sf v_o=60\]
