The motion of a body weighing 3 kg is given by the equation x = 3 + 4t + 2t ^ 2. What is the projection of the momentum of the body

The motion of a body weighing 3 kg is given by the equation x = 3 + 4t + 2t ^ 2. What is the projection of the momentum of the body onto the OX axis at the moment of time 3 s?

We know that S = So + Vot + at ^ 2/2, where
S-distance
So- start coordinate
Vo-Initial Velocity
t-time
a-acceleration
We also know that t = 3
Now we substitute:
S = 3 + 4 * 3 + 4 * 2 ^ 2/2 = 23
Answer: S = 23 m
