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
You can find the distance using the equation: distance = (final velocity)^2 / (2 * acceleration). Square the final velocity, divide it by twice the acceleration to get the distance traveled before coming to a stop.
v2 - u2 = 2as so that a = (v2 - u2)/2s where u = initial velocity v = final velocity s = distance a = acceleration
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.
Average speed = 1/2 (initial speed + final speed) Time = (distance)/(average speed)
To find the final velocity when given the acceleration and time, you can use the formula: final velocity initial velocity (acceleration x time). Simply plug in the values for acceleration and time, and calculate the final velocity.
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.
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.
To find the distance using final velocity and minimum acceleration, you can use the formula: distance = (final velocity)^2 / (2 * acceleration). Simply square the final velocity, then divide by 2 times the minimum acceleration to get the distance traveled.
velocity is a vector quantity. Its magnitude is given by (velocity)= (distance)/(time)
