Explanation:
(a) The net force in the y direction is the sum of the individual forces.  Taking up to be +y:
∑F = Lift − Weight
∑F = 100,000 N − 75,000 N
∑F = 25,000 N
(b) Since the net force is not 0, the forces are unbalanced.
(c) Since the lift is greater than the weight, the plane will rise.
(d) The net force in the x direction is the sum of the individual forces.  Taking forward to be +x:
∑F = Thrust − Drag
∑F = 200,000 N − 23,000 N
∑F = 177,000 N
(e) Since the net force is not 0, the forces are unbalanced.
(f) Since the thrust is greater than the drag, the plane will accelerate.
 
        
             
        
        
        
Answer:
I think it would be the 3rd or 4th one. 
 
        
             
        
        
        
Answer:
x ≈ 56 m
Explanation:
vertical initial velocity = = 25 m/s* sin(30°)= 12.5 m/s
 = 25 m/s* sin(30°)= 12.5 m/s
height = h

t- time is found solving quadratic equation.
horizontal velocity = 
Horizontal velocity is constant, so distance 
 
        
             
        
        
        
(1 cal/g °C) x (4000 g) x (45 - 25)°C = 80000 cal = 80 kcal. So the answer is 80 kcal .
