Answer 1

don't you want to finish your other question first?

Answer 2

I finished that one my self

Answer 3

for this problem do i devide the multiply

Answer 4

are you trying to figure out the acceleration in the form of km/s or km/2s?

Answer 5

\[20m/s^2\]

Answer 6

I ma trying to find out the acceleration in seconds

Answer 7

would it be squared?

Answer 8

no

Answer 9

So it's simple. Do u want an physics equation or shall explain it in maths.

Answer 10

I just want a answer

Answer 11

sorry i did not see the units
\[5/9m/s^2 \] should be the right ans

Answer 17

rvg what are you talking about

Answer 18

It would be..
