Answer:
72
Step-by-step explanation:
In order to find the acceleration we need first to defined it, so:
acceleration=((final velocity)-(initial velocity))/time interval

But (vf-vi) actually represents the velocity change, so (vf-vi)/dt represents the velocity change rate. This means that in our case:


In conclusion the acceleration is
, without units just 72.
Answer:
How I answered this was
Line up 812 divided by 12
So 81 divided by 12 = 72
Subtract 81 - 72
Which would equal 9
then bring down the two in 812
Which would make it 92
Then divide that by 12
which would equal 84
the subtract 92 - 84
that would equal 8
put a decimal then bring down a 0
that would be 80 then divide 80 by 12
that would be 7 which would equal 8 again
so our answer would be 67.6 continuous.
