Question

An aeroplane starts from rest with an acceslaration of 3m/s and takes a run for 35s before taking off. what is the minimum length of runway and with velocity the plane took off

Answer 1

length of plane=1837.5

use s=ut+1/2at*t

u=0,a=3,t=35

find s ...and thats the answer

Answer 2

Answer:

Explanation:

given

t=35 sec

a=3m/s2

=u=0

=s= ut+1/2at2

=s=0*t+1/2*3*35*35

=s=3*35*35 upon 2

=3675/2

=1837.5

Let v is the took off velocity so,

v=u+at

v = 0+3*35

v=105 m/s
