The final velocity is (the initial velocity) plus (the acceleration multiplied by the time).
It depends on what information you have. Also, velocity can be negative - it just means that the object is travelling in the direction opposite to the positive direction for the velocity vector.
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.
Without distance, you have to know time, initial velocity, and acceleration, in order to find final velocity.
a = (v2 - u2)/2s where a is the acceleration between the initial point in time and the final point in time, u is the initial velocity v is the final velocity s is the distance travelled
Yes.
Final velocity = Initial velocity +(acceleration * time)
Vf = Vi + at Where Vf = final velocity Vi = initial velocity a = acceleration t = time
Accelerating...or was accelerating.

final velocity-initial velocity --------------------------------- time
Final velocity is the your last velocity traveled. Example if you travel 50m/s your final velocity is 50m/s because its the last velocity traveled, 0m/s is the initial velocity. Its not your total velocity because if u start running at 5m/s then accelerated 25m/s, your final velocity is NOT 30m/s. It is 25m/s. Also, your velocity change is 20m/s(25-5).
yes it does. u can calculate the final velocity of the falling object with the following eqn: initial potential energy= final kinetic energy or mgh = 1/2mv2 where m=mass, h = height,v=final velocity
Negative acceleration.
You subtract the initial velocity from the final velocity and divide by the time interval.
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.
The object opposes the air and while falling of the object the initial velocity will become zero , and the final velocity will have some value's this is how air will resist the velocity of falling object ...........
Its final velocity will be zero when it reaches maximum potential energy.
