Yeah has to be because rate only increases when direction of velocity is equal to acceleration10 was D, I'm pretty sure.
1.D
2.B
3.A
4.A
5.C
6.D
7.B

Jfc I didn't think and used acceleration as speed fml.Yes 10 was d since
a=+2
v=-3
va=-6 since negative therefore decelerating/decreasing speed
Also as v=-3 (negative) therefore at that time particle was moving left of origin
I don't even know anymore. Still hoping it's (B).im pretty sure 10 was b
remember velocity = speed WITH direction
and -acceleration means negative/going down
so i think it's B
Alright if you insist...Well some one upload the paper. I forgot to grab mine from the room lol.
drop kicks the answers are as follows;-
1. D
2. B
3. A
4. A
5. C
6. D
7. B
8. B
9. C
10. D
These are certain correct answer !!!!!!!!!!!!!!!!!
If a > 0, the particle is travelling at an increasing speed.I don't even know anymore. Still hoping it's (B).
explain? Is it B?Congrats faggot, you got question 6 wrong... so much for calling everyone a drop kick
Please dear god let this be true; this is what I did but everyone else was posting different answers so I got worried.^ To be honest, i freaked out when I saw the question, but realised that there was a much simpler way of finding the answer (I stared at it for a few minutes): substitute values into the equation! The answer (if i remember correctly) is A - Substituting in x=pi/2 (and the other values in the graph), you find that y=o, meaning the first one is correct.
Note: you must be in radians^ To be honest, i freaked out when I saw the question, but realised that there was a much simpler way of finding the answer (I stared at it for a few minutes): substitute values into the equation!

You remember incorrectly x=pi/2 is not on any of the graphs, but I get what you mean. If you know the formula it is much quicker to do it that way though^ To be honest, i freaked out when I saw the question, but realised that there was a much simpler way of finding the answer (I stared at it for a few minutes): substitute values into the equation!

Apologies, pi/3You remember incorrectly x=pi/2 is not on any of the graphs, but I get what you mean. If you know the formula it is much quicker to do it that way though
According to my friend it was 4.5 lolbtw what was 14d? I had a stab at: a=4??
