Final answer:
The statement is true; the final velocity V of an object under constant acceleration can be calculated using the formula V²=v²+2as, which relates final velocity to initial velocity, acceleration, and displacement.
Step-by-step explanation:
The statement 'The final velocity V of an object under constant acceleration can be found using formula V²=v²+2as' is True. This equation is derived from the principles of kinematics and reflects the relationship between an object's final velocity (V), initial velocity (v), acceleration (a), and the displacement (s) it covers under constant acceleration.
The equation V = V0 + at shows that final velocity depends on the magnitude of the acceleration and how long it lasts. When the acceleration (a) is zero, the final velocity (V) will be equal to the initial velocity (v0), indicating that the object is moving at a constant velocity.
If the acceleration is negative, it means the object is decelerating, and thus, the final velocity will be less than the initial velocity. These findings align with our intuition about the effects of acceleration on an object's motion.
