Question

3. What do the symbols Vi and Vf represent?
A. velocity in two different directions
B. the velocity of object i and object f
C. change in velocity
D. initial velocity and final velocity​

Answer 1

Answer:

a t is the amount by which the velocity increases from vi to vf after a time t. Note that if a = 0, vf = vi, i.e., velocity is constant. g is the special symbol we use for the acceleration due gravity. Since we know how to deal with constant acceleration, we can also solve problems involving free fall.

Answer 2

Answer:

Because initial velocity is represented by Vi and final velocity is represented by Vf, D is the right answer.

Explanation:

The velocity at time interval t = $0$ is indicated by the symbol Vi It is the speed at which the motion begins.

The final velocity, on the other hand, is a vector quantity that quantifies the speed and direction of a moving body after it has attained maximum acceleration.

Vi = Vf– at.

The rate of change of velocity is referred to as acceleration.
