Answer:

Explanation:
Since the formula for kinetic energy of an object is:

Where m is the mass of the object and v is the speed. We can substitute m =  kg and v = 17900m/s:
kg and v = 17900m/s:

 
        
             
        
        
        
Answer:0.302
Explanation:
Given
mass of crate m=27 kg
Force required to set crate in motion is 80 N
Once the crate is set  in motion 56 N is require to move it with constant velocity
i.e. 80 N is the amount of force needed to just overcome static friction and 56 is the kinetic friction force
thus  

where  is the coefficient of static friction and N is Normal reaction
is the coefficient of static friction and N is Normal reaction





 
        
             
        
        
        
Answer:
Option C
Explanation:
We have to check range of all options first
For A:
Largest Value: 5
Smallest Value: 1
So range = Largest value - smallest value
5-1 = 4
For B:
Largest Value: 6
Smallest Value: 4
Range = 6-4 = 2
For C:
Largest Value: 9
Smallest Value: 1
Range = 9-1 = 8
For D:
Largest Value = 9
Smallest Value = 3
Range = 9-3=6
So, the data set in option C has the largest range
