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).
