Answer:
Maximum Range of Projectile
Now that the range of projectile is given by R = u 2 sin 2 θ g , when would be maximum for a given initial velocity . Well, since is a constant, for a given , depends on and maximum value of is . So, R m a x = u 2 g and it is the case when θ = 45 ∘ because at θ = 45 ∘ , 2 θ = 1 .
