V2 = V1 + a*t.
160 = V1 + 4*40, V1 = 0.

Final velocity = Initial velocity + (Acceleration * Time)
Plugging in the given values, the final velocity is the takeoff speed and the acceleration is 4 m/s, we can rearrange the formula:
Initial velocity = Final velocity - (Acceleration * Time)
So, if the takeoff speed is the final velocity and it takes 40 seconds to reach that speed, we can calculate:
Initial velocity = Takeoff speed - (4 m/s * 40 s)
I'm going to do some quick calculations here... *typing sounds*... and there you have it! The initial velocity of the jet is the result of that equation. Enjoy your flight!

v = u + at
Where:
v = final velocity
u = initial velocity
a = acceleration
t = time
In this case, the acceleration (a) is given as 4 m/s^2 and the time (t) is given as 40 seconds.
By substituting the known values into the formula, we can solve for the initial velocity (u):
Final velocity (v) is the takeoff speed.
v = u + at
takeoff speed = u + (4 m/s^2)(40 s)
Since the takeoff speed is achieved at the end of the 40-second period, the final velocity (v) is equal to the takeoff speed. Therefore, we can rewrite the equation as:
takeoff speed = u + (4 m/s^2)(40 s)
Now, we can solve for the initial velocity (u):
u = takeoff speed - (4 m/s^2)(40 s)
Please provide the value for the takeoff speed so that I can calculate the initial velocity.

\(v = u + at\)
Where:
- \(v\) is the final velocity (takeoff speed)
- \(u\) is the initial velocity (what we want to find)
- \(a\) is the acceleration
- \(t\) is the time taken
Given:
- Acceleration (\(a\)) = 4 m/s²
- Time taken (\(t\)) = 40 s
Substituting these values into the formula, we get:
\(v = u + at\)
Rearranging the formula to solve for \(u\):
\(u = v - at\)
Now let's plug in the values:
\(u = \text{takeoff speed} - (4 \, \text{m/s²})(40 \, \text{s})\)
Takeoff speed is not provided in the question, so we'll have to use the given information to find it. Since the jet is accelerating at a constant rate, we can use another formula to find the final velocity:
\(v = u + at\)
Since we want to find the takeoff speed (final velocity), we can use:
\(v = u + at\)
Given:
- Acceleration (\(a\)) = 4 m/s²
- Time taken (\(t\)) = 40 s
- Initial velocity (\(u\)) = ?
Substituting these values into the formula, we get:
\(v = u + at\)
Rearranging the formula to solve for \(v\):
\(v = u + at\)
\(v = u + (4 \, \text{m/s²})(40 \, \text{s})\)
Now we have an equation for both \(u\) and \(v\). By substituting the value of \(v\) from the second equation into the first equation, we can solve for \(u\).
