chameleons catch insects with their tongues, which they can extend to great lengths at great speeds. A chameleon is aiming for an insect at a distance of 16 cm. The insect will sense the attack and move away 45 ms after it begins. In the first 45 ms, the chameleon's tongue accelerates at 345 m/s2 for 20 ms. Does its tongue reach the 16 cm extension needed to catch the insect during this time?
