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 on it. The figure shows the acceleration magnitude a versus time t for the acceleration phase of the launch in a typical situation. The indicated acceleration are a2= 380 m/s^2 and a1= 120 m/s^2.

Required:
What is the outward speed of the tongue at the end of the acceleration phase?

where's the following? you gotta add it to know what the choices are

explanation:

answer: (431,2)

step-by-step explanation:

current and voltage can both be different in different parts of a circuit so it matters where you place the ammeter and voltmete

force is based upon mass and acceleration.the statement is not always true.

it can be explained from newton's second law of motion.

as per newton's second law of motion the rate of change of momentum is directly proportional to the applied force and takes place along the direction of force.

mathematically it can be written as -

                                              ⇒      

here   k is the proportionality constant whose value is 1.

                                                            [a is the acceleration=dv/dt]

hence we see that force not only depends on mass and acceleration but also on velocity and rate of change of mass. force f will depend on mass and acceleration only when mass is constant.

hence the statement that force is based upon mass and acceleration is false.
