Answer:
range becomes 4 times
Explanation:
We know that the range of a projectile is given as:
[tex]R=\frac{u^2.\sin(2\theta)}{g}[/tex]
where:
[tex]R=[/tex] range of the projectile
[tex]u=[/tex] initial velocity of projectile
[tex]\theta=[/tex] initial angle of projection form the horizontal
g = acceleration due to gravity
When the initial velocity of launch is doubled:
[tex]R'=\frac{(2u)^2.\sin(2\theta)}{g}[/tex]
[tex]R'=\frac{4u^2.\sin(2\theta)}{g}[/tex]
[tex]R'=4R[/tex]
range becomes 4 times
