G: s or v = 20 m/s; d = 150 m
E: a =
S: In this case, we don't have the time so we're going to solve for the time first.
So we already have the time, which is, 7.5 s. Now, we can already solve for the acceleration.
Or we can convert them into their significant values. In this case, the lowest SF is 1 so we round it off in its 1 SF.
A: 3 m/
