Answer:
They would keep on moving but unless being acted upon or stop slowly because of the friction 
Explanation:
 
        
             
        
        
        
KE = 1/2mv^2
KE= 1/2(2)(5)^2
KE= 25 J
        
             
        
        
        
Answer:
b. able to travel through a vacuum.
Explanation:
The most distinguishing factor of an electromagnetic waves is that they are able to travel through a vacuum. 
These waves do not require materials in a medium for propagation. 
- Electromagnetic waves are formed by the propagation of the electric and magnetic fields. 
- They vibrate at an angle of 90° . 
- They are unlike like mechanical waves that requires that requires materials in medium for their propagation.
