A bullet fired from a gun can pierce through a thick wooden board but the same bullet thrown with a blow of hand can't pierce in the board.

Ratio of the ranges of the bullets fired from a gun ( of constant muzzle speed ) at angle theta, 2 theta &4 theta is found in the ratio x:2:2 , then the value of x will be ( Assume same muzzle speed of bullets )
