The trajectory of a projectile is the path it follows during its motion. While a projectile's trajectory may resemble other shapes in certain specific situations, the most accurate and general description is that it follows a parabolic path in the absence of air resistance. Options (A) and (B) are incorrect as they describe different geometric shapes. Option (C) is incorrect because the presence of air resistance can distort the parabolic path.
The correct answer is (D) a parabola in the absence of air resistance.
A particle is projected at an angle of \( 30^\circ \) from horizontal at a speed of 60 m/s. The height traversed by the particle in the first second is \( h_0 \) and height traversed in the last second, before it reaches the maximum height, is \( h_1 \). The ratio \( \frac{h_0}{h_1} \) is __________. [Take \( g = 10 \, \text{m/s}^2 \)]
