A jumbo jet must reach a speed of 360 km/h on the runway for takeoff. What is the least constant acceleration needed for takeoff form a 1.80 km runway?

I couldn't figure out which equation to use

I think there are a couple of equations involved here.

You're given s=1.8km and v_final =360km/hr

You'll need to look for equations that relate s,v,a and t

You might use s=(1/2)at^2 and v=at

You'll need to do some manipulating and substituting. You might also want to convert the km/hr to m/sec.

I'll be glad to check your work.
