∙ 11y agoIf 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.

∙ 11y agoYou 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
The equation that relates the distance traveled by a constantly accelerating object to its initial velocity, final velocity, and time is the equation of motion: [ \text{distance} = \frac{1}{2} \times (\text{initial velocity} + \text{final velocity}) \times \text{time} ] This equation assumes constant acceleration.

This equation represents the final velocity squared when an object is accelerating from an initial velocity over a certain distance. It is derived from the kinematic equation (v^2 = u^2 + 2as), where (v) is the final velocity, (u) is the initial velocity, (a) is the acceleration, and (s) is the distance traveled.
Well, (final velocity) = (initial velocity) + (acceleration x time)
When calculating acceleration to find the change in velocity, you subtract the initial velocity from the final velocity. The formula for acceleration is: acceleration = (final velocity - initial velocity) / time.

You can use the equation: Displacement = (final velocity squared - initial velocity squared) / (2 * acceleration). Plug in the values of final velocity, initial velocity, and acceleration to calculate the displacement.
Final velocity = (Initial velocity) + (time)(acceleration)
To find an object's acceleration, you need its initial velocity, final velocity, and the time it takes to change from the initial velocity to the final velocity. The formula for acceleration is (final velocity - initial velocity) / time elapsed.
To find acceleration, you subtract the initial velocity from the final velocity and then divide by the time taken to achieve the change in velocity. The formula for acceleration is (final velocity - initial velocity) / time.
You can use the equation: distance = (initial velocity + final velocity) / 2 * time. This formula assumes constant acceleration.
zero because the initial and final velocity is constant . so,difference bet. final velocity and initial velocity is zero
