ELP Math Angry Birds
Logan's Duck Dynasty Demolition Fort
Put your cursor on point C. Drag it around until you find the trajectory motion you think the turtle will knock over the Duck's Fort in a single blow.
Make a note of the angle in green and multiply the first number in the C equation by 8 to determine how many inches to pull back on the slingshot.
Take careful aim because you only have one shot to get the math right!
