Math Problem Statement
An airplane starts from rest and accelerates at a constant 2.90 m/s2 for 25.92 s before leaving the ground. What is its displacement during this time?
Solution
To find the displacement of the airplane during its acceleration, we can use the kinematic equation for displacement:
Where:
- is the displacement,
- is the initial velocity (which is 0 since the airplane starts from rest),
- is the acceleration (),
- is the time ().
Since the initial velocity , the equation simplifies to:
Now, plugging in the values:
Let's calculate that.# Given values a = 2.90 # acceleration in m/s^2 t = 25.92 # time in seconds
Using the equation for displacement: d = 1/2 * a * t^2
displacement = 0.5 * a * t**2 displacementThe displacement of the airplane during the 25.92 seconds of acceleration is approximately .

Here are 5 related questions to expand your understanding:
- How would the displacement change if the acceleration was doubled?
- What would be the final velocity of the airplane after this acceleration period?
- How would the displacement change if the time was reduced to 15 seconds?
- If the airplane continued accelerating for an additional 10 seconds, what would its displacement be then?
- How can we calculate the distance if the airplane had an initial velocity?
Tip: When solving kinematic equations, always ensure the correct substitution of units to avoid calculation errors.
