Member advised to use the homework template for posts in the homework sections of PF.

So this question has two parts. The first I got without any trouble:

"Two objects move with initial velocity of -8.00 m/s, final velocity of 16.0 m/s, and constant accelerations. (a) The first object has displacement 20.0 m. Find its acceleration."

I used The formula V

The second part is where I have some difficulty:

"(b) The second object travels a total distance of 22.0 m. Find its acceleration."

Before someone says to solve the same way as part A, I should point out part B says "distance", not "displacement".

If someone could give some insight on which equations to use and if calculus would be required that would be great. If someone wants to actually solve it that would also be fantastic for me to check my work with.

Thanks!

I used The formula V

_{f}^{2}=V_{i}^{2}+2aΔx and got an answer of 8 m/s^{2}.The second part is where I have some difficulty:
