Answer:
Tiene que patear el balón cerca del nivel del suelo para conseguir el gol.
Explicación:
Leo Messi necesita patear el balón no en el aire, en el nivel del suelo para poder meter el gol para el equipo. Delante del fútbol hay muchos jugadores del equipo contrario dispuestos a detener el tiro libre de Leo Messi. Cuando Leo Messi patea el balón en el aire, los jugadores también saltan en el aire para detener el tiro libre que atraviesa la cabeza y para conseguir el gol Leo Messi tiene que evitar patear el balón en el aire y patear el balón cerca del nivel del suelo. que puede atravesar a los jugadores oponentes cuando lo saltan para detener el balón a través de sus cabezas para que el balón pase por debajo de sus pies y llegue a la portería.
 
        
             
        
        
        
Answer:
(a)  ,

(b) When  , object is slowing down, when
, object is slowing down, when  object is speeding up.
 object is speeding up.
Explanation:
(a) To get the velocity function, we need to take the derivative of the position function.

To get the acceleration function, we need to take the derivative of the velocity function.

(b) The object is slowing down when velocity is decreasing by time (decelerating) hence a < 0

On the other hand, object is speeding up when a > 0

Therefore, when  , object is slowing down, when
, object is slowing down, when  object is speeding up.
 object is speeding up.
 
        
             
        
        
        
Mass in physics is in kg and mass in chemistry is in grams. Therefore a person's mass is kg
        
                    
             
        
        
        
The amount of gold atoms could be calculated by dividing the
total weight of the gold with the mass of a single gold atom. Just convert the
given weight to grams then divide it with 3.27x10^-22 grams. The answer would
be 7.22x10^20. 
 
        
                    
             
        
        
        
Answer:
A) 5.2 x 10³ N
B) 8.8 x 10³ N
Explanation:
Part A)
 = weight of the craft in downward direction = tension force in the cable when stationary = 7000 N
 = weight of the craft in downward direction = tension force in the cable when stationary = 7000 N 
 = Tension force in upward direction
 = Tension force in upward direction 
 = Drag force in upward direction = 1800 N
 = Drag force in upward direction = 1800 N
Force equation for the motion of craft is given as 
 -
 -  -
 -  = 0
 = 0 
7000 - 1800 -  = 0
 = 0
  = 5200 N
 = 5200 N 
  = 5.2 x 10³ N
 = 5.2 x 10³ N
Part B)
 = weight of the craft in downward direction = tension force in the cable when stationary = 7000 N
 = weight of the craft in downward direction = tension force in the cable when stationary = 7000 N 
 = Tension force in upward direction
 = Tension force in upward direction 
 = Drag force in downward direction = 1800 N
 = Drag force in downward direction = 1800 N
Force equation for the motion of craft is given as 
 -
  -  -
 -  = 0
 = 0 
 - 7000 - 1800  = 0
 - 7000 - 1800  = 0
  = 8800 N
 = 8800 N 
  = 8.8 x 10³ N
 = 8.8 x 10³ N
