There are three things that can be represented on a motion map
These three things are:
1)Motion
2)Acceleration 
3)Velocity
 
        
             
        
        
        
Answer:
Distance traveled during this acceleration will be 6950 m 
Explanation:
Wear have given maximum speed tat will be equal to final speed of the car        v = 278 m/sec
Constant acceleration 
As the car starts initially starts from rest so initial velocity of the car u = 0 m/sec
From third equation of motion 
Putting all values in equation 

s = 6950 m 
So distance traveled during this acceleration will be 6950 m 
 
        
             
        
        
        
Answer:
F = 47.6 N
Explanation:
- Newton's 2nd law can be expressed as the rate of change of the total momentum, respect of time, as follows:
        
- So, in order to find the average force exerted by the skater on the wall, we can find the change in momentum due to the force exerted by the wall (which is equal and opposite to the one exerted by the skater), and  divide it by the time interval , as follows:
        
        ⇒ Fsk = 47.6 N (normal to the wall)
 
        
             
        
        
        
Answer:
4.384 * 10^13
Explanation:
Given the expression :
[(6.67 * 10^-11) * (1.99 * 10^30)] ÷ [(1.74*10^3)*(1.74*10^3)]
Applying the laws of indices 
[(6.67 * 1.99) *10^(-11 + 30)] ÷ [(1.74 * 1.74) * 10^3+3]
13.2733 * 10^19 ÷ 3.0276 * 10^6
(13.2733 / 3.0276) * 10^(19 - 6)
4.3840996 * 10^13
= 4.384 * 10^13
