Answer 1

Answer:

(c) Initial position of velocity of any object.

Answer 2

Initial position of velocity of any object  

Explanation:

• INITIAL POSITION is a position from which  a point a body is released or started. e.gm when u start a car. FINAL POSITION is that position a body stopped or covered a distance from a point to another point.

• Displacement Δx is the switch in position of an object: Δx=xf−x0, where Δx is displacement, xf is the final position, and x0 is the initial position.

• it is  denoted by (Δ) which mean “change in” whatever quantity follows it; thus, Δx means change in position (final position less initial position).
