Question

Why the trajectory of a projectile is parabola............
Pls ans my que fast.....
1st ans will be marked as brainliest ​

Answer 1

Answer:

Projectile motion is parabolic because the vertical position of the object is influenced only by a constant acceleration, (if constant drag etc. is also assumed) and also because horizontal velocity is generally constant. is quadratic, and therefore describes a parabola.

Answer 2

Answer:

Prove that the trajectory of a projectile is parabolic, having the form y = ax + bx2 . To obtain this expression, solve the equation x = v0x t for t and substitute it into the expression for y = v0y t – (1 / 2)gt2 (These equations describe the x and y positions of a projectile that starts at the origin.)

hope u understand it.....
