(a) Define horizontal range of a projectile.
(b) The horizontal range, R, of a projectile is given by the equation R = (frac{u^2 sin 2theta}{g})
(i) what does (theta) in the equation represent?
(ii) for what value of (theta) would R be maximum?
Explanation
(a) Horizontal range is the horizontal distance between the point of projection and the point of landing
(b) (i) (theta) = angle of projection
(ii) R is maximum when (theta) = 45°
