Homework Help: Tongue extends 18cm find accelaration

  1. Oct 5, 2008 #1
    1. The problem statement, all variables and given/known data
    When a chameleon captures an insect, its tongue extends 18 cm in 0.10 s.

    (a) Find the acceleration of the chameleon's tongue, assuming it to be constant.
    (b) Let Δx be the amount that the chameleon's tongue moves during the first 0.050 s. Compare Δx with 9 cm.
    pick one
    1 Δx < 9 cm
    2 Δx > 9 cm

    Support your conclusion with a calculation.
    Δx = ? cm

    My answers were wrong how? why? what equation am I suppose to use?


    This was wrong
