An engineer is trying to design a runway for an airport. He knows that airplanes have the ability to accelerate at 3.3 m/s ^ 2 and it takes 35 seconds for an airplane to lift off the ground. If his blueprint includes a runway that is 1600 meters in length is it long enough

NO

Step-by-step explanation:

Given

Acceleration

Time

Runway length

using

where s=length of runway

u=initial velocity

a=acceletation

t=time

Substituting values we get

Therefore length is not enough

answer:   b

step-by-step explanation:

x2 = 16

x can not be a negative number because 16 is positive

the only answer would be positive 8
