Here is the info.
s = 150m
a = ?
t = ?
vi = 0
vf = 27
Here is what I did:
[tex]27 = at[/tex]
[tex]27/t = a[/tex]
Put a into another unsolved equation.
[tex]150 = 1/2(27/t)t^2[/tex]
[tex]11.1 = t[/tex]
Put the known variable into the first equation.
[tex]27 = a(11.1)[/tex]
[tex]2.43 = a[/tex]
All I did was take variables, and insert it into it's derivative, or antiderivative. I'm getting different answers using other methods. Can someone explain if this is incorrect?
