A tropical ant called the trap-jaw ant snaps its jaws closed to push off the ground and jump into the air. These ants are a bit more than a centimeter long and their jaws are each about 3 mm long. To jump, they open the jaws to a 180 degree angle, bend their head down to place them against the ground and snap them closed. The ends of the jaws reach a speed of 225 [km/hr] after moving through a 90 degree arc. a) How far has the tip of each jaw traveled? {arc length of a quarter of a circle with a radius of the length of the jaw.} 4.71[mm] b) What is the average acceleration of the tip of the jaw? This will be a huge number! {To calculate this, assume the acceleration was constant from v=0 to v – 225 [km/hr] This is a way to “cheat properly” if we only have information about the final motion and aren’t interested in details of the motion during
