a 1,400 kg airplane encounters a 200 n headwind that slows it down. if the airplane was originally traveling 230 m/s, how long (in s) will it take the headwind to slow the airplane to 120 m/s?

Respuesta :

A 1,400 kg airplane encounters a 200 newton headwind that slows it down. if the airplane was originally traveling 230 m/s .  It take 12 minutes for the headwind to slow the airplane to 120 m/s

Force = mass * acceleration

- 200 N = 1400 * ( change in speed / time interval )

- 200= 1400 * (120 - 230 / time )

-200 = 1400 * ( -110 / time )

time = 770 seconds = 12 minutes

It take 12 minutes for the headwind to slow the airplane to 120 m/s
