Without distance, you have to know time, initial velocity, and acceleration, in order
to find final velocity.
v2 - u2 = 2as so that a = (v2 - u2)/2s where u = initial velocity v = final velocity s = distance a = acceleration
if acceleration a, initial velocity vi and final velocity vf is given , then time could be found by applying formula t=vf-vi/aand if distance s and velocity v is given then t=s/v
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.

vf2 = vi2 + 2ad, where vf is final velocity, vi is initial velocity, a is acceleration, and d is displacement. Solve for a.vf = vi + at, where t is time time. Solve for a.
v = 2s/t - u where u=initial velocity, v=final velocity, s = distance and t = time
v2 - u2 = 2as so that a = (v2 - u2)/2s where u = initial velocity v = final velocity s = distance a = acceleration
If you take initial velocity(Vi) to be zero and the final velocity (Vo) to be a known. Puting the knowns into a triganonomical equation and solving for the value of D would give an answer
Average speed = 1/2 (initial speed + final speed) Time = (distance)/(average speed)
You can only know the distance for sure if acceleration or deceleration is constant. Add the start and end velocities and divide by two and then multiply by the time to get your distance.
you cannot figure out the change in velocity given just the distance and loss of potential energy. you need more information
if acceleration a, initial velocity vi and final velocity vf is given , then time could be found by applying formula t=vf-vi/aand if distance s and velocity v is given then t=s/v
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.
velocity is a vector quantity. Its magnitude is given by (velocity)= (distance)/(time)

Veloicty is distance divided by time, for a object moving in a given direction. If direction is not given, then it is speed.
