when a chameleon captures an insect its tingue car extend 16 cm in 0.10 s. (a) Find the magnitude of the tongue's acceleration, assuming it to be constant.(b) In the first 0.050 s, dones the tongue extend 8.0 cm, more than 8.0 cm, or less than 8.0 cm? Support your conclusion with a calculation.

d=1/2 a t^2 solve for a.
b) at t=.05s, d=1/2 a t^2 you know a.
