If you traveled 25 miles in 2 minutes, your average speed was 25 miles per 2 minutes or 750 miles per hour. If your rate of deceleration was constant, your initial speed was two times 750 miles per hour or 1500 mph.
I do not have enough information to determine your initial velocity because I don't know what direction you were going, and velocity is speed with direction.
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.
Well, (final velocity) = (initial velocity) + (acceleration x 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).
Final Velocity- Initial Velocity Time
Final velocity = Initial velocity +(acceleration * time)

Final velocity = (Initial velocity) + (time)(acceleration)
zero because the initial and final velocity is constant . so,difference bet. final velocity and initial velocity is zero
Kinematics. Final velocity squared = initial velocity squared + 2(gravitational acceleration)(displacement)
The final velocity is (the initial velocity) plus (the acceleration multiplied by the time).
Final Velocity- Initial Velocity Time
v = 2s/t - u where u=initial velocity, v=final velocity, s = distance and t = time
Vf = Vi + at Where Vf = final velocity Vi = initial velocity a = acceleration t = time
A change in velocity can be effected only by acceleration. Therefore, if the acceleration is zero, there is no change, so final velocity equals initial velocity.
