Please help me I am the above person :(
If the velocity is uniform, then the final velocity and the initial velocity are the same. Perhaps you meant to say uniform acceleration. In any event, the question needs to be stated more precisely.
both the magnitudes and the directions of the initial and final velocities are the same.
Here are the velocity equations D= (vi+vf/2)t D=vit + 1/2 at^2 V^2=Vi^2 + 2ad V= vi+at a= (vf-vo)/t According to your question, use V^2=Vi^2 + 2ad v= Final velocity vi= initial velocity a= acceleration d= displacement

Yes. You could have two objects with the same final velocity (momentum, if they have mass), but having each one accelerated differently. Imagine object A starts from 5 m/s, and is accelerated over 1 second with acceleration of 20 m/s2 to attain a final velocity of 25 m/s. Now, imagine object B starts from 15 m/s, and gets an acceleration over 1 second of 10 m/s2 to attain the final velocity of 25 m/s. Both end up with the same velocity, but had different accelerations.

apply conservation of momentum theory- m1v1=m2v2 where m1 is the initial mass, m2 is the final mass, v1 is the initial velocity and v2 is the final velocity.
Deceleration is the rate of decrease of velocity with respect to time. It is the negative of acceleration. The formula for deceleration is the same as that of acceleration, only that the acceleration is represented as negative. The formula is: - (deceleration) = (final velocity) - (initial velocity) time Therefore, (deceleration) = (initial velocity) - (final velocity) time
If you throw an object up, and assume that air resistance is negligible, knowing the initial velocity is enough. One way to do this is to use conservation of energy. Calculate the energy from the initial velocity, then insert it in the formula for gravitational potential energy.Same for final velocity - the final speed is the same as the initial speed. If you know the work done, you already have the first half of the above steps solved.
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.
Both the gliders will be travelling at exactly the same speed as the initial velocity but in opposite directions.
Distance alone is not enough to tell you velocity final. (If it could, then all of the thousands of runners who finish in the same marathon would all cross the finish line at the same speed.) Besides distance, you would also need velocity initial, and either acceleration or time.
No. V=v0 +at is the formula for velocity, the acceleration 'a' can be the same but the initial velocity v0 may be different. If v0 is the same for the two automobiles , the velocity would be the same.

Initial velocity = m/s, Final velocity =m/s Distance traveled x = mIn this example, the items labeled on the diagram are considered primary: if one of them is changed, the others remain the same. The data in the boxes may be changed, and the calculation will be done when you click outside the box, subject to the constraints described. If the average velocity is directly changed, the final velocity is adjusted for consistency. If the acceleration or time is changed, then the distance is allowed to change.Distance x = m Initial velocity v0 = m/s Final velocity v = m/s Average velocity = m/s Acceleration a = m/s^2 Time t = s

The first answer is backward. Acceleration = (final velocity - initial velocity)/total time. For deceleration the formula is the same, the answer will just be negative.Agreed. In physics, there is no "deceleration", only negative acceleration.a = Δv / ΔtThere is no equation for "deceleration" as suggested below.Deceleration=(original velocity-final velocity)/TimeDeceleration In MotionDeceleration = inital speed - final speed / total time taken
