A projectile is projected at $\displaystyle 30^{\circ}$ from horizontal with initial velocity $\displaystyle 40 \mathrm{~ms}^{-1}$. The velocity of the projectile at $\displaystyle \mathrm{t}=2 \mathrm{~s}$ from the start will be :
(Given $\displaystyle \mathrm{g}=10 \mathrm{~m} / \mathrm{s}^2$ )
Official answer
From NTA’s final answer key for this paper.
(2)
$\displaystyle 20 \sqrt{3} \mathrm{~ms}^{-1}$
