Question

a projectile is fired with initial speed u at some angle ∅ has time of flight T . if the initial speed be halved at the same angle of projection then the time of flight will be ?​

Answer 1

Answer:

As Range=

g

u

2

sin2θ

or Rαu

2

[θ=constant]

And for u initial velocity and θ initial angle Range=R

Then for 2u initial velocity and θ initial angle range 4R.
