Question

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 22 cm. The insect will sense the attack and move away 60 ms after it begins. In the first 60 ms, the chameleon’s tongue accelerates at 250 m/s2 for 20 ms, then travels at constant speed for the remaining 40 ms. Does its tongue reach the 22 cm extension needed to catch the insect during this time?

Answer 1

the average velocity during the acceleration is 125m/s
distance=125*.02cm+250*.04=
= 5cm+10cm
check that, I was guessing he caught it.
