Answer: C. -1.16 meters/second2
Explanation:
A= v/t (velocity/time)
in this case: v=7 and t=6
So, A= 7/6
A=1.16
The graph is decreasing so accelleration would be negative
A= <u>-1.16 meters/second2</u>
<u>Option C!</u> ; )

Answer:
Explanation:
We shall take the help of vector form of displacement . Taking east as i and north as j 
4.0m N = 4 j 
7.5 m E = 7.5 i 
6.8 m S = - 6.8 j 
3.7 m E, = 3.7 i 
3.6 m S = - 3.6 j
 5.3 m W = - 5.3 i 
3.7 m N, = 3.7 j 
5.6 m W = - 5.6 i 
4.4 m S = - 4.4 j
4.9 m W = -  4.9 i 
Total displacement = 4j +7.5 i -6.8j+3.7i-3.6j-5.3i+3.7j-5.6i-4.4j-4.9i
= -4.6 i -7.1 j 
magnitude of displacement = 
= 8.46 m 
Direction 
Tanθ = 7.1/ 4.6 
θ = 57⁰ south of west . 
distance walked = 4+7.5 +6.8+3.7+3.6+5.3+3.7+5.6+4.4+4.9
= 49.5 m 
 
        
                    
             
        
        
        
football hemets have pads that are filled with air and thick foam so when they are hit the foam asorbs the hit and the air keeps the hard outer shell of the helmet from hiting the players head
 
        
                    
             
        
        
        
Well there is many ways we are not evolved as much as we think we are from being we die from a lot of diseases to world hunger and other things to be honest humans are far from being really evolved in life we really need to focus on cures and solving world hunger and fighting among ourselves 
Hope this helps
        
             
        
        
        
Rarefraction.
Crest- tallest spot on transverse wave.
Trough- shortest point on transverse wave.
Compression - spot on a compressional wave where the waves are closer together.
Rarefraction - spot on a compressional wave where the waves are farther apart.
