A projectile is thrown with initial velocity of (3 i +4 j ) m / s. Here ' i ' is along the horizontal direction and ' j ' is assumed in vertical…
A projectile is thrown with initial velocity of $\displaystyle (3 \hat{i}+4 \hat{j}) \mathrm{m} / \mathrm{s}$. Here ' $\displaystyle \hat{i}$ ' is along the horizontal direction and ' $\displaystyle \hat{j}$ ' is assumed in vertical direction. The equation of the trajectory is - (Take $\displaystyle g=10 \mathrm{~m} / \mathrm{s}^2$ )
Official answer
(1)
$\displaystyle 9 y=12 x-5 x^2$
