(a) Define horizontal range of a projectile.
(b) The horizontal range, R, of a projectile is given by the equation R = \(\frac{u^2 sin 2\theta}{g}\)
(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°
