Q. A particle starts from the origin at $t = 0$ with an initial velocity of $3.0\,\hat{i}\,m / s$ and moves in the $x-y$ plane wit h a constant acceleration $\left(6.0\,\hat{i}+4.0\,\hat{j}\right)m /s^{2}$. The $x$ -coordinate of the particle at the instant when its $y$- coordinate is $32\, m$ is $D$ meters. The value of $D$ is :
Solution:
