An airplane on a runway accelerates at 4.0 meters/second2 for 28.0 seconds before takeoff. How far does the plane travel on the runway before takeoff?

Answer:

there is a formula . s=ut+ 0.5at^2
s = distance travelled(to be found)
u= initial velocity =0
a= acceleration= 4
t=28 sec
put in the equation
u get s= 0
28 + 0.54(28)^2 = 0+ 1568 = 1568 m
