When a chameleon captures an insect, its tongue can extend 16 cm in 0.10 s.

(a) Find the magnitude of the tongueâ€™s acceleration, assuming it to be constant.

(b) Let Δx be the amount that the chameleon's tongue moves during the second 0.050 s. Calculate Δx

a step by step process works just fine without the answers. thanks

a)

x = 1/2 * a * t^2

where x is distance, a is acceleration, and t is time

16 = 1/2 * a * 0.1^2

Solve for a (it's units will be cm/s)

b) Now that you know the acceleration calculate x when t = 0.1 seconds (0.1 = 0.05 + 0.05), and then calculate x when t = 0.05 seconds. subtract these two to get delta x
