There are a few formulas you can use to calculate final velocity, depending on the information given:

If given initial velocity, acceleration, and time, use:

vfinal = vinitial + at

Where:

vfinal is the final velocity

vinitial is the initial velocity

a is the acceleration

t is the time

If given initial velocity, change in velocity, and time, use:

vfinal = vinitial + Δv

Where:

Δv is the change in velocity

If given displacement, initial velocity, acceleration, and time, use:

vfinal = √(vinitial2 + 2aΔx)

Where:

Δx is the displacement

If given initial and final displacements and time, use:

vfinal = Δx/t

So in summary, to calculate final velocity you need:

Initial velocity + Acceleration + Time

OR

Initial velocity + Change in velocity

OR

Initial velocity + Acceleration + Displacement + Time

OR

Initial/final displacement + Time

Then you can use the appropriate formula, plug in the known values, and solve for final velocity (vfinal).

Hope these formulas and explanations help! Let me know if you have any other questions.
