You can't.
"I traveled 100 miles and finished at a speed of 40 mph. What was my starting speed ?"
Impossible without another piece of information. Something like the length of time
the trip took, or the acceleration during the trip. Something like that.
Use s=ut+0.5at^2 (^2 notation for squared)Or calculate the final velocity from the known variables (Initial Velocity, Acceleration and Time)v=u+at Where V = Final Velocity, u = Initial Velocity, a = Acceleration, t = TimeThen calculate displacement (s) using s=0.5(u+v)t
The relationship between acceleration, initial velocity, final velocity, displacement, and time in a given motion is described by the suvat equations. These equations show how these variables are related and can be used to calculate one variable if the others are known. The equations are used in physics to analyze and predict the motion of objects.
The formula for calculating acceleration is: acceleration (final velocity - initial velocity) / time elapsed.
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.
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.

s = u + at s = displacement u = initial velocity a = acceleration t = time rearrange to give u = s - at and sub in values

v = 2s/t - u where u=initial velocity, v=final velocity, s = distance and t = time
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.
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 can find the final speed by using the formula: final speed = initial velocity + (acceleration * time). Plug in the given values for initial velocity, acceleration, and time into the formula to calculate the final speed.
Use the formula Acceleration = (final velosity - initial velocity)/ time.
Without distance, you have to know time, initial velocity, and acceleration, in order to find final velocity.
To find acceleration, you take Vi [Initial Velocity] and you subtract if from Vf [Final Velocity.] (Vi - Vf) If they Vi and Vf are already given, you take the two givens and you subtract them from each other. Vi minus Vf. Do not do Vf minus Vi or it will be wrong. After you do that, you divide your answer from T [Time] (Vi - Vf) a= _____ t Once you get your answer, that will be your acceleration.
