The body moves along the Ox axis with constant acceleration. The projection onto the Ox axis of the initial velocity of the body

The body moves along the Ox axis with constant acceleration. The projection onto the Ox axis of the initial velocity of the body Vox = 2.5 m / s, the projection of the acceleration ax = – 3.0 m / s ^ 2. What will be the modulus of the final velocity of the body when the projection of its movement becomes Δr = -1.0 m

The body will be at the same point, but with a different direction of movement with the same speed.
Now let’s find its speed
1m = (V ^ 2-6.25m / s) / 6 m / s ^ 2
V ^ 2 = 12.25 (m / s) ^ 2
V = 3.5m / s
Answer: V = 3.5m / s
