Velocity and Acceleration Extra Credit Problem

[FreshmanInPhysics]

Homework Statement

d=Vi t + 1/2at^2
What do each of these mean? Show that this is true

d=vt-Solve

v=Vf+Vi/2 - Substitute Vf with Vf= Vi+at

Homework Equations

v= average speed
Vi=initial speed
Vf= final speed

The Attempt at a Solution

Vit: This represents the initial velocity at said time elapsed
1/2at^2: This represents half the acceleration at said time elapsed squared

d/t=v

v=2Vi+at/2

Welcome to the PF.

Your post is a bit jumbled. Are you in a calculus-based physics class? Calculus is one way you can show that this equation is correct.
