For angles of projection of a projectile at angle (45^(@) - theta) and (45^(@)+ theta) , the horizontal ranges described by the projectile are in the ratio of :

Galileo writes that for angles of projection of a projectile at angles (45 + theta) and (45 - theta) , the horizontal ranges described by the projectile are in the ratio of (if theta le 45 )

If theta is the angle between the velocity and acceleration of a projectile at a point of its path, its value when the projectile is at the highest point is :

A projectile is projected from the ground by making an angle of 60^@ with the horizontal. After 1 s projectile makes an angle of 30^@ with the horizontal . The maximum height attained by the projectile is (Take g=10 ms^-2)

From the ground, a projectile is fired at an angle of 60 degree to the horizontal with a speed of 20" m s"^(-1) The horizontal range of the projectile is
