A projectile is given an initial velocity of $\widehat{\mathrm{i}}+2\widehat{\mathrm{j}}$ The cartesian equation of its path is :$\left(\mathrm{g}=10\mathrm{m}/{\mathrm{s}}^2\right)$

• A

  $\mathrm{y}=2\mathrm{x}-5{\mathrm{x}}^2$

• B

  $\mathrm{y}=\mathrm{x}-5{\mathrm{x}}^2$

• C

  $4\mathrm{y}=2\mathrm{x}-5{\mathrm{x}}^2$

• D

  $\mathrm{y}=2\mathrm{x}-25{\mathrm{x}}^2$
