We assume you mean the work done in order to change the velocity of the moving mass.
Easiest way is to calculate the change in the kinetic energy of the moving mass, and realize
that it's equal to the amount of work either put into the motion of the mass or taken out of it.
Initial kinetic energy = 1/2 m Vi2
Final kinetic energy = 1/2 m Vf2
Change in kinetic energy = 1/2 m ( Vf2 - Vi2) <== that's the amount of work involved.
If the final velocity is greater than the initial velocity, the change in kinetic energy is positive,
and represents work done by the pusher to speed up the mass.
If the final velocity is less than the initial velocity, the change in kinetic energy is negative, and
represents work done by the mass and absorbed by the pusher, as the mass slowed down.
Without distance, you have to know time, initial velocity, and acceleration, in order to find final velocity.
Use the formula Acceleration = (final velosity - initial velocity)/ time.
the formula for finding acceleration is final velocity, minus initial velocity, all over time. So if you have the acceleration and initial speed, which is equal to the initial velocity, you must also have time in order to find the final velocity. Once you have the time, you multiply it by the acceleration. That product gives you the difference of the final velocity and initial velocity, so then you just add the initial velocity to the product to find the final velocity.
The final velocity is (the initial velocity) plus (the acceleration multiplied by the time).
You can't. You need either the final velocity or the acceleration of the object as well, and then you can substitute the known values into a kinematics equation to get the initial velocity.

v = 2s/t - u where u=initial velocity, v=final velocity, s = distance and t = time
Use the formula Acceleration = (final velosity - initial velocity)/ time.
You use the information you're given, along with the equations and formulas you know that express some kind of relationship between the information you're given and the initial and final velocity.

Kinematics. Final velocity squared = initial velocity squared + 2(gravitational acceleration)(displacement)
Average speed = 1/2 (initial speed + final speed) Time = (distance)/(average speed)
You subtract the initial velocity from the final velocity and divide by the time interval.
Yes.
The initial acceleration of an object can be found by calculating the change in velocity over time. This can be done by dividing the final velocity by the time taken to reach that velocity. The formula for initial acceleration is: initial acceleration = (final velocity - initial velocity) / time.
