Show that a gun will shoot woll shoot three times as hith when elevated at an angle of ` 60^(@)` as when fired at an angle ` 30^(@)` but will have the same horizontal rande.

Show that a given gun will shoot three times as high when elevated at an angle of 60^(@) as when fired at angle of 30^(@) but will carry the same distance on a horizontal plane.

Show that a given gun will shoot three times as high when elevated at an angle of 60^@ as when fired at angle of 30^@ but will carry the same distance on a horizontal plane.

A particle is projected with speed 'u' at an angle 60^@ with horizontal, then find the speed when its angle with horizontal changes to 30^@ .

A particle is thrown at time t=0 with a velocity of 10 m/s at an angle of 60^(@) with the horizontal from a point on an incline plane, making an angle of 30^(@) with the horizontal. The time when the velocity of the projectile becomes parallel to the incline is :

A particle at a height h from the ground is projected with an angle 30^@ from the horizontal, it strikes the ground making angle 45^@ with horizontal. It is again projected from the same point with the same speed but with an angle of 60^@ with horizontal. Find the angle it makes with the horizontal when it strikes the ground

A gun fires a shell and recoils horizontally . If the shell travels along the barrel with speed v , the ratio of speed with which the gun recoils if (i) the barrel is horizontal (ii) inclined at an angle of 30^(@) with horizontal is

A gun fires a shell and recoils horizontally . If the shell travels along the barrel with speed v , the ratio of speed with which the gun recoils if (i) the barrel is horizontal (ii) inclined at an angle of 30^(@) with horizontal is

Two particle are projected with same initial velocities at an angle 30^(@) and 60^(@) with the horizontal .Then

Two particle are projected with same initial velocities at an angle 30^(@) and 60^(@) with the horizontal .Then
