Question

if it is to be airboure after a takeoff run of 240 m? B) How long does it take the aircraft to become airborne?

Answer 1

the equations are
d(t)=.5*a*t^2

and v(t)=a*t

d(t)=240 m and v(t)=120 km/hr
convert v(t) to m/s
then substitute v(t) into the d(t) equation

240=.5*(120/3.6)*t
solve for t and then solve for a
