A projectile is projected at $30 ^ { \circ }$ from horizontal with initial velocity $40 \mathrm {~m} \mathrm {~s} ^ { - 1 }$. The velocity of the projectile at $\mathrm { t } = 2 \mathrm {~s}$ from the start will be:
(1) $40 \sqrt { 3 } \mathrm {~m} \mathrm {~s} ^ { - 1 }$
(2) Zero
(3) $20 \mathrm {~m} \mathrm {~s} ^ { - 1 }$
(4) $20 \sqrt { 3 } \mathrm {~m} \mathrm {~s} ^ { - 1 }$
