Assertion: For projection angle tan^(-1)(4) , the horizontal range and the maximum height of a projectile are equal. Reason: The maximum range of projectile is directely proportional to square of velocity and inversely proportional to acceleration due to gravity.

If R and H represent horizontal range and maximum height of the projectile, then the angle of projection with the horizontal is

The velocity at the maximum height of a projectile is half of its initial velocity of projection. The angle of projection is
