Question

What is projectile show that the path of the projectile is a parabola?

Answer 1

Answer:

Suppose a projectile of mass ‘m’ is projected with velocity ‘u’ at an angle θ with the ground.

The horizontal component of the initial velocity is, ux = u cosθ [this remains constant]

The horizontal displacement at any time ‘t’ is, X = ux t = ut cosθ

=> t = X/(u cosθ)

The vertical component is given by, uy = u sinθ

The vertical displacement at any time ‘t’ is, Y = uy t – ½ gt 2 = ut sinθ – ½ gt2

=> Y = u[X/(u cosθ)]sinθ – ½ g[X/(u cosθ)]2

=> Y = X tanθ – gX2 /[2u2 cos2 θ]

Which is the equation of a parabola. So, the path of the projectile is parabolic.
