An airplane accelerates down a runmway at 2.9 m/s/s for 38.5 seconds
until if lifts off the ground. Determine the distance traveled on the runway
before taking off. (Answer to the nearest one's place. Enter only the
number of meters, no units) *

Sagot :

  • initial velocity=u=0m/s^2
  • Acceleration=2.9m/s^2
  • Time=t=38.5s

Distance be s

[tex]\\ \sf\longmapsto s=ut+\dfrac{1}{2}at^2[/tex]

[tex]\\ \sf\longmapsto s=0(38.5)+\dfrac{1}{2}(2.9)(38.5)^2[/tex]

[tex]\\ \sf\longmapsto s=1.45(1482.25)[/tex]

[tex]\\ \sf\longmapsto s=2149.26m[/tex]
