object starts with an initial velocity of magnitude $4.0 \mathrm{~m} / \mathrm{s}$ and accelerates at $4.0 \mathrm{~m} / \mathrm{s} 2$ in the same direction as the velocity for 6.0 seconds. It then accelerates at $2.0 \mathrm{~m} / \mathrm{s}^{2}$ in the opposite direction, until its velocity is the same as the initial value. What is the total distance covered? (Hint: make a graph of velocity versus time.)
A) $67 \mathrm{~m}$
B) $216 \mathrm{~m}$
C) $192 \mathrm{~m}$
D) $96 \mathrm{~m}$
E) $288 \mathrm{~m}$
