Calculate Velocity with Given/No Acceleration - Get Help Here!

[r-soy]

what is that mean :

Use Formula v = changing of x / changing of v when don't given acceleration :

but use Formula :
v = v0 + at when given acceleration

please I want the help

thanks

I think you mean:

speed = distance / time
If the speed is constant, so no acceleration

And final V = starting V + acceleration * time
When there there is acceleration
