An object is projected at an angle of `45^(@)` with the horizontal. The horizontal range and the maximum height reached will be in the ratio.

Choose the correct option (i) The speed of a projectile at its maximum height is half of its initial speed. The angle of projection is 60^(@) . (ii) A missile is fired for maximum range with an initial velocity of 20 m//s , the range of the missile is 40 m . (iii) A ball is projected with a kinetic energy E at an angle of 45^(@) to the horizontal. At the highest point during its flight, its kinetic energy will be E//2 . (iv) An object is projected at an angle of 45^(@) with horizontal. The horizontal range and the maximum height will be in the ratio 4:1

Find the angle of projection for which the horizontal range and the maximum height are equal.

A body is projected from the ground at an angle of tan^(-1) ((8)/(7)) with the horizontal. The ratio of the maximum height attained by it to its range is

Two projectile are projected with the same velocity. If one is projected at an angle of 30^(@) to the horizontal. The ratio if maximum heights reached, is:

Two projectiles are projected with the same velocity. If one is projected at an angle of 30^(@) and the other at 60^(@) to the horizontal, then ratio of maximum heights reached, is

Two bodies are projected with the same velocity. If one is projected at an angle of 30^(@) and the other at an angle of 60^(@) to the horizontal, the ratio of the maximum heights reached is

Two projectiles are projected with the same velocity. If one is projected at an angle of 30^@ and the other at 60^0 to the horizontal, then the ratio of maximum height reached, is
