The range of a projectile is R when the angle of projection is `40^(@)`. For the same velocity of projection and range, the other possible angle of projection is

The range of a projectile is R when the angle of projection is 30^@ . For the same velocity of projection and range the other possible angle of projection is:

Range of a projectile is R, when the angle of projection is 30^(@) . Then, the value of the other angle of projection for the same range is

The range of a projectile for a given initial velocity is maximum when the angle of projection is 45^(@) . The range will be minimum, if the angle of projection is

Show that the horizontal range of a projectile is same for two angles of projection . Is the sum of maximum heights for these two angles dependent on the angle of projectile ?

Keeping the angle of projection constant, if the velocity of projection is doubled, the horizontal range

What are the possible angles of projection with the same velocity to have same range?
