A salamander of the genus Hydromantes captures prey by
Chapter , Problem 68(choose chapter or problem)
A salamander of the genus Hydromantes captures prey by launching its tongue as a projectile: The skeletal part of the tongue is shot forward, unfolding the rest of the tongue, until the outer portion lands on the prey, sticking to it. Figure 2-39 shows the acceleration magnitude a versus time t for the acceleration phase of the launch in a typical situation. The indicated accelerations are \(a_{2}=400 \mathrm{m} / \mathrm{s}^{2}\) and \(a_{1}=100 \mathrm{m} / \mathrm{s}^{2}\). What is the outward speed of the tongue at the end of the acceleration phase?
