STATEMENT-1 : A particle is projected with a velocity 0.5sqrt(gR_(e )) from the surface of the earth at an angle of 30^(@) with the vertical (at that point ) its velocity at the highest point will be 0.25sqrt(gR_(e )) because STATEMENT-2 : Angular momentum of the particle earth system remains constant.
