Answer:

Explanation:
The acceleration of an object is given by:

where
v is the final velocity
u is the initial velocity
t is the time interval it takes for the velocity to change from u to v
For the rocket in this problem,
u = 20,000 m/s
v = 24,000 m/s
t = 55.0 - 5.0 = 50.0 s
Substituting,

 
        
             
        
        
        
Answer:
 P₁ = 2.215 10⁷ Pa, F₁ = 4.3 106 N, 
Explanation:
This problem of fluid mechanics let's start with the continuity equation to find the speed of water output
         Q = A v
         v = Q / A
The area of a circle is
        A = π r² = π d² / 4
Let's look at the speeds at each point
        v₁ = Q / A₁ = Q 4 /π d₁²
        v₁ = 10 4 /π 0.5²
        v₁ = 50.93 m / s
        v₂ = Q / A₂
        v₂ = 10 4 /π 0.25²
        v₂ = 203.72 m / s
Now we can use Bernoulli's equation in the colon
        P₁ + ½ ρ v₁² + ρ g y₁ = P₂ + ½ ρ v₂² + ρ g y₂
Since the tube is horizontal y₁ = y₂. The output pressure is P₂ = Patm = 1.013 10⁵ Pa, let's clear
        P₁ = P2 + ½ rho (v₂² - v₁²)
       P₁ = 1.013 10⁵ + ½ 1000 (203.72² - 50.93²)
       P₁ = 1.013 10⁵ + 2.205 10⁷
       P₁ = 2.215 10⁷ Pa
la definicion de presion es
       P₁ = F₁/A₁
      F₁ = P₁ A₁
      F₁ = 2.215 10⁷ pi d₁²/4
      F₁ = 2.215 10⁷ pi 0.5²/4
      F₁ = 4.3 106 N
