Answer:
the net force is the same direction as the acceleration 
Explanation:
so toward the center of the circle about which the object is constantly moving.
 
        
             
        
        
        
Answer:
Due to the resistance of air, a drag force acts on a falling body (parachute) to slow down its motion. Without air resistance, or drag, objects would continue to increase speed until they hit the ground. The larger the object, the greater its air resistance. Parachutes use a large canopy to increase air resistance. Also, Once the parachute is opened, the air resistance overwhelms the downward force of gravity. The net force and the acceleration on the falling skydiver is upward. An upward net force on a downward falling object would cause that object to slow down. The skydiver thus slows down.

The farther away an object is from the Sun the slower it orbits around it. The closer an object is from the Sun the faster it orbits around it.
 
        
             
        
        
        
Answer:
  x = 25 / μ     [ ft]
Explanation:
To solve this exercise we can use Newton's second law.
Let's set a reference system where the x axis is parallel to the road
Y axis  
        N_B + N_A - W_van - W_load = 0
        N_B + N_A = W_van + W_load
X axis
      fr = ma
      a = fr / m
the total mass is
         m = (W_van + W_load) / g
the friction force has the expression
       fr = μ N_{total}
       fr = μy (W_van + W_load)
we substitute
       a = μ (W_van + W_load)     
       a = μ g
taking the acceleration let's use the kinematic relations where the final velocity is zero
        v² = v₀² - 2 a x
        0 = v₀² -2a x
         x =  
 
         x =  
         x =  
         x = 25 / μ     [ ft]
