An airplane is initially traveling at \( 119 \mathrm{~m} / \mathrm{s} \) when begins to accelerate at \( 25.6 \mathrm{~m} / \mathrm{s}^{2} \) in order to reach \( 233 \mathrm{~m} / \mathrm{s} \). How far does the plane travel during this time?

Step-by-step Solution
Given:
- Initial velocity of the airplane, \( u = 119 \, \text{m/s} \)
- Acceleration of the airplane, \( a = 25.6 \, \text{m/s}^2 \)
- Final velocity of the airplane, \( v = 233 \, \text{m/s} \)
We can use the kinematic equation to find the distance traveled by the airplane during this time:
\[ v^2 = u^2 + 2as \]
Substitute the given values into the equation:
\[ 233^2 = 119^2 + 2 \times 25.6 \times s \]
Now, we can solve for the distance \( s \) traveled by the airplane.
Solve the equation by following steps:
- step0: Solve for \(s\):
\(233^{2}=119^{2}+2\times 25.6s\)
- step1: Simplify:
\(233^{2}=14161+51.2s\)
- step2: Swap the sides:
\(14161+51.2s=233^{2}\)
- step3: Calculate:
\(14161+51.2s=54289\)
- step4: Move the constant to the right side:
\(51.2s=54289-14161\)
- step5: Subtract the numbers:
\(51.2s=40128\)
- step6: Divide both sides:
\(\frac{51.2s}{51.2}=\frac{40128}{51.2}\)
- step7: Divide the numbers:
\(s=\frac{3135}{4}\)
The distance traveled by the airplane during this time is \( 783.75 \, \text{m} \).
Quick Answer
The distance traveled by the airplane is \( 783.75 \, \text{m} \).
