At what angle to the horizontal should an object be projected so that the maximum height reached is equal to the horizontal range.

The velocity of a projectile is 15m/s .At what angle to the horizontal should it be projected so that it cover maximum horizontal distance?

Velocity of a projectile is 10 ms^(-1) . At what angle to the horizontal should it be projected so that it covers maximum horizontal distance ?

A javelin is thrown with an initial velocity v_0 at an angle theta with the horizontal. Find the angle of projection at which the maximum height attained by the javelin is equal to the horizontal range.

For a projectile projected at an angle _____the maximum height and horizontal range are equal.

Two bodies are projected at angles 30^(@) and 60^(@) to the horizontal from the ground such that the maximum heights reached by them are equal then a) Their times of flight are equal b) Their horizontal ranges are equal c) The ratio of their initial speeds of projection is sqrt3:1 d) Both take same time to reach the maximum height.

A projectile is projected from ground such that the maximum height attained by, it is equal to half the horizontal range.The angle of projection with horizontal would be
