$4.0 \mathrm{~kg}$ Mass Has a Velocity Of $10 \mathrm{~m} / \mathrm{s}$

$4.0 \mathrm{~kg}$ mass has a velocity of $10 \mathrm{~m} / \mathrm{s}$ to the EAST. The mass undergoes a constant acceleration of $4.0 \mathrm{~m} / \mathrm{s} 2$ to the WEST for $3.0 \mathrm{sec}$ . What is the velocity of the mass at the end of the $3.0 \mathrm{sec}$ interval?

A) $2.0 \mathrm{~m} / \mathrm{s}$ to the EAST
B) $2.0 \mathrm{~m} / \mathrm{s}$ to the WEST
C) $22 \mathrm{~m} / \mathrm{s}$ to the EAST
D) $0.0 \mathrm{~m} / \mathrm{s}$
E) $22 \mathrm{~m} / \mathrm{s}$ to the WEST
