21. Cooking an omelet on a boat is tricky because the tilting of the boat can cause the omelet to slip off the flat griddle. If the coefficient of static friction between the omelet and the griddle is 0.05, what is the largest angle (measured from the horizontal) that the griddle can tilt before the omelet starts to slide? A) 3° B) 6° C) 9° D) 12° E) 15°
