An airplane is moving at a speed of 75m/s as it lands on a runway. if the runway is 500 m long what is the acceleration of the plane as it slows to a stop

Respuesta :

Answer:

-5.625 m/s^2

Explanation:

Use the kinematic equation [tex]v_{f}^{2} = v_{o}^{2} + 2ad[/tex]

Substitute the values and solve for a.

0^2 = 75^2 + a 2 (500)

0 = 5625 + 1000a

-5625 = 1000a

-5.625 = a
