Answer:
43km/h to m/s = 11.9444
Explanation:
1 km = 1000 m; 1 hr = 3600 sec. To convert km/hr into m/sec, multiply the number by 5 and then divide it by 18.
 
        
             
        
        
        
Your "weight" is the name you give to that gravitational force.
So your question actually says:
           "Your weight just got three times stronger !
             What happens to your weight ?"
        
             
        
        
        
Answer:
 E_total = 3 N / A
Explanation:
The electric field is a vector magnitude so when adding we must use vectors, in this case as the initial field E = 4N / c goes towards the axis axis and the field created by the fixed charge (E1) is also on the axis x we can add in scalar form.
                 E_total = E + E₁
the expression for the field of a point charge is
                 E₁ = k q₁ / r²
for the point x = 2m, they do not say that the total field is zero, so the charge q1 must be negative
                  E_total = E -k q₁ / r₂
we substitute
                    0 = E - k q₁ / r²
                    q₁ =  
let's calculate
                    q₁ =  
                    q₁ = 1.78 10⁻⁹ C
now we can calculate the field for position x = 4 m
                    E_total = 4 - 9 10⁹  1.78 10⁻⁹ / 4²2
                    E_total = 3 N / A

44.64m
Explanation:
Given parameters: 
Mass of the car = 1500kg 
Initial velocity = 25m/s 
Frictional force = 10500N 
Unknown: 
Distance moved by the car after brake is applied = ? 
Solution: 
The frictional force is a force that  opposes motion of a body. 
To solve this problem, we need to find the acceleration of the car. After this, we apply the appropriate motion equation to solve the problem. 
      -Frictional force = m x a 
the negative sign is because the frictional force is in the opposite direction
 m is the mass of the car
  a is the acceleration of the car
     a =  =
 =  = -7m/s²
 = -7m/s²
 Now using;
    V² = U² + 2as 
    V is the final velocity 
    U is the initial velocity 
    a is the acceleration
    s is the distance moved
   0² = 25² + 2 x 7 x s 
   0 = 625 - 14s 
   -625 = -14s 
       s = 44.64m
