I want to find the velocity value but I can't find it, am I doing something wrong?

Help me.

Sure, you can use the root function. With a guess value:

Or the 'bracketed' form, where you provide the limits of a range within which to find v1:

And you can (first) solve the problem symbolically, to find both solutions:

Then fill in the data:

Success!

Yes you are. You forgot to set the unit for v1 in its guess value

v1:= 1 m/s^2

 

Success!

Is there any other way to find the velocity without using the solve block?

How about using the "root" function in one of its two flavours ?

You may also use the symbolic "solve", but I would suggest doing so before you define your units and create a function in all unknowns for v1.
