A stone is thrown from ground level at an angle of θ above the horizontal such that the ratio of the x-component of its initial velocity to the y-component of its initial velocity is 2. The stone strikes a wall 6 m away and at a height of 2 m above the ground. Calculate the initial speed of the stone. 

A. 25 m/s 

B. 30 m/s 

C. 10 m/s 

D. 20 m/s 

E. 15 m/s
