What should be the angles of projection to obtain maximum height and m

1.	What should be the angles of projection to obtain maximum height and maximum time of flight?
Answer» The maximum height attained by the projectile is given by, h = u² sin 2θ/2g It is maximum when sinθ is maximum,i.e., sinθ = 1 or, θ = 90° The time of flight of a projectile is given by T = 2u sinθ/g It is maximum when sinθ is maximum i.e., sinθ = 1 or, θ = 90°.

Answer»

The maximum height attained by the projectile is given by,

h = u² sin 2θ/2g

It is maximum when sinθ is maximum,i.e.,

sinθ = 1 or, θ = 90°

The time of flight of a projectile is given by

T = 2u sinθ/g

It is maximum when sinθ is maximum

i.e., sinθ = 1

or, θ = 90°.
