What is the Velocity at Half the Distance with Constant Acceleration?

[siddharthmishra19]

A body starts moving with velocity Vo and constant acceleration a. After moving a certain distance, it attains a velocity of V. What is its velocity as it moves half the distance?

Vo = 1m/s
V = 7m/s

 

[Chi Meson]

Start this way:

find the formula that relates initial velocity, final velocity, displacement, and acceleration. (Time is NOT a concern in this problem because a) it will not be constant and b) it is neither given nor asked for in the problem.)
