Physics

The range of the projectile is 4675 m and the maximum height is 2024 m.

A projectile is the motion of an object which is thrown into space and subjected to the acceleration due to gravity.

Given that:

Initial speed (u) = 230 m/s, acceleration due to gravity (g) = 9.8 m/s², angle (θ) = 60°

$Range=\frac{u^2sin2\theta}{g} =\frac{230^2*sin(2*60)}{9.8} =4675\ m$

$Maximum\ height(h)=\frac{u^2sin^2\theta}{2g} =\frac{230^2*sin^2(60)}{2*9.8} =2024\ m$

$Speed\ at\ impact=\sqrt{2gh}=\sqrt{2*9.8*2024} =199\ m/s$

The range of the projectile is 4675 m and the maximum height is 2024 m.
