Starting from rest , an airplane (mass= 12,000 kg) accelerates 1,700 meters along a runway . What is the average net force on the plane if its final speed is 55 m/s ?

I know F = m a, however I can't read off acceleration either since there's a velocity and a distance instead of time it took?

anonymous · Answer

instead of velocity and the time it took to reach it
there's a velocity and a distance

how to get the acceleration then ??

anonymous · Answer

v^2 - u^2 = 2 as 

using this equation?

should work

anonymous · Answer

is u the displacement?

ganeshie8 · Answer

u is initial velocity, 
here its 0

ganeshie8 · Answer

assuming, plain started from rest
