Question

The equation of motion of a projectile is given by $y = \sqrt{3}x - 5x^2$ (in SI units). What is the angle of projection?

Professor PC Thomas Classes · Answer

The general equation of trajectory is $y = x	an	heta - \frac{gx^2}{2u^2\cos^2	heta}$. Comparing coefficients, $	an	heta = \sqrt{3}$, which means $	heta = 60^\circ$.
