Question

?

Answer 1

these are the kinematics equations and they come up a lot in physics so I would suggest bookmarking/writing this down

since you are given initial velocity (0), final velocity, and distance, you can use equation #4 and find acceleration

Answer 2

0=30+8

Answer 3

v0 is the initial velocity so v0 = 0 not v

don't forget to include the exponents

Answer 4

v0=30+8

Answer 5

make sure you are including the exponents, the 2 and the delta x

Answer 6

v0=30+(2)8x

Answer 7

keep in mind that v and v0 are squared

Answer 8

OKay so let me just the values straight

Answer 9

V^2=8
V20=0
2ax=30

Answer 10

distance is just delta x not 2*a*delta x

v is 8, not v^2

Answer 11

a=17

Answer 12

delta x = 30
v = 8
v0 = 0

Answer 13

check your calculations again

Answer 14

I'd hate to be annoying, but...
Do you think its possible you could start typing your questions in the question box? It makes it more searchable, and easier to organize later.

Answer 15

The whole question?

Answer 16

I guess..

Answer 17

The choices doesn't have to be, but I would prefer at least the question if possible x'D

Answer 18

8=0+2a+30

Answer 19

@Ultrilliam okay

Answer 20

almost\[v^{2} = v_0 + 2a /\Delta x\] (ignore that extra slash after the a

v is 8, so v^2 is 8^2 not just 8

Answer 21

so 8^2 = 0 + 2a(30), solve for a

Answer 22

16/15

Answer 23

so D

Answer 24

good
