S = 4 * 8 - 1/2 * 64 = 0

The object just returns to its original starting point

It started out at 8 m/s which was reduced to 0 m/s after 4 sec

In 4 more seconds it was moving at -8 m/s, just the opposite of where it started

Disclaimer: I just answered this, here is the answer again!
*Used copy paste from my own answer as it is a repeated question, no copied work*

3. A
The relation between V and I at constant R is;V=IR, so it is a direct linear relation.
4. A
This is another direct linear relation as P=IV.
5. D
The relation between P, R, and V is P=, so P is inversely proportional to R.
6.B
The relation between P,I, and R is , so P is directly proportional to the square of I.

Please note that y:x relations are always straight lines while  relations are parabolic lines.

Hope this helps!
