Answer:
The acceleration is  
Explanation:
From the question we are told that 
    The lift up speed is  
     The distance covered for the take off run is 
Generally from kinematic equation we have that
       
Here u is the initial  speed of the aircraft with value 0 m/ s give that the aircraft started from rest 
So

Answer:
0.488  m  
Explanation:
If θ be the angle ladder makes with the plane 
cos θ = 1.2 / 5 
Tan θ = 4.04 
Let the height a person of weight 600 N  can climb be h from the ground . 
Distance from the base point  where ladder touches the floor  = h / tanθ
= h / 4.04 
Total reaction force = total downward force 
R = 200 + 600 
800 N 
Frictional force = μ R
= .2 x 800
= 160 N 
Taking moment of force about the point on the ladder  where it  touches the floor  and balancing them 
200 x 1.2 x .5 + 600 x   h / tanθ  = μ R x  1.2 / tanθ ( reaction  at the top point of ladder where it touches the wall is  R₁ and 
R₁ =μ R   )
= 200 x 1.2 x .5 + 600 x   h / tanθ  = 160 x 1.2 / tanθ
120  - 600 h / 4.04 = 47.52
120 - 47.52 = 600 h / 4.04
72.48= 148.51 h 
h = 0.488  m  
=

For an adiabatic process Heat is not allowed to cross the boundary of the system.
So:
E.no heat flows into or out of the system
