an airplane accelerates down a runway at 5.20 m/s^2 for 32.8s until it finally lifts off the ground. determine the distance traveled before takeoff

Respuesta :

Answer:

7,272.7m

Explanation:

Our knowns:

a = 5.2m/s^2

t = 32.8s

[tex]V_{i}[/tex] = 0 m/s

Our Unknowns:

Distance (x): ?

We can use displacement formula:

ΔX = [tex]V_{i}[/tex] t + [tex]\frac{1}{2}[/tex] a [tex]t^{2}[/tex]

Plug in knowns:

X = 0 + 1/2 ((5.2)(32.8))^2

Answer:

ΔX = 7272.7m

(I beleive this should be right) let me know if it helped!
