Answer:
8.03 m/s
Step-by-step explanation:
Given:
Final takeoff speed (v) = 45 m/s
Length of the runway (s) = 126 m
Initial speed of the jet (u) = 0 m/s (note: this isn't directly given but it is implied)
To find:
Acceleration of the jet (a)
Solution:
Here, we use the formula v² - u² = 2as
We have all the variables except a, so we can solve it for a.
Substituting the values of v, u, and s, we get:
(45)² - (0)² = 2(a)(126)
2025 = 252(a)
Therefore a = 2025/252 which comes out to be around 8.03 m/s2 which is the final answer.
Hope this helps! :D
