Explanation:
Given that,
Initial speed of a car, u = 12 m/s
Aceleration, a = -1.6 m/s²
(a) The displacement of car after 6 seconds is :

(b) The displacement of the car after 9 seconds is :

Hence, this is the required solution.
 
        
             
        
        
        
Answer:
0.25A
1.0A
2.5A
Explanation:
this is only for the calculated current column on edge
 
        
                    
             
        
        
        
If the group of all forces acting on an object is balanced, 
then the effect of all of them is the same as if there were 
no forces at all on the object.  In that case, the object 
continues moving in a straight line at a constant speed.
        
             
        
        
        
His speed per hour was 5.8km and the total of 6 hours is 35km
        
                    
             
        
        
        
<span>The centripetal force for such an arrangement can be found through the equation Fc = mv^2/r where m is the mass of the rotating object, v is that object's velocity, and r is the radius of rotation. In this case, we know that the maximum Fc that can be tolerated by the cord is 64N. Thus we set the equation up and solve for the value of v for which Fc = 64.
   64 = 0.4*(v^2)/1
 64/0.4 = 160 = 
v^2
v = sqrt(160) = 12.65 m/s
   At any speed faster than 12.65 m/s, the cord will break.</span>
