True, if you move something forward at 100 miles an hour but your on something moving backwards 100 miles an hour you up staying in the same location, aka zero velocity.
 
        
                    
             
        
        
        
We could take the easy way out and just say
(110 kW) x (3 hours) = 330 kilowatt hours .
But that's cheap, and hardly worth even 5 points.
If we want to talk energy, let's use the actual scientific unit of energy.
________________________________________________
" 110 kw " means 110,000 watts = 110,000 joules/second .
(3 hours) x (3600 sec/hour) = 10,800 seconds.
(110,000 joules/second) x (10,800 seconds) = 1.188 x 10⁹ Joules
 That's
==>  1,188,000,000 joules
==>  1,188,000 kilojoules
==>  1,188 megajoules
==>  1.188 gigajoules
Atsa nawfulotta energy !  
It goes back to that "110 kw appliance" that we started with.  
That's no common ordinary household appliance.  110 kw is something like
147 horsepower.  In order to bring 110 kw into your house, you'd need to
take 458 Amperes through the 240-volt line from the pole.  Most houses 
are limited to 100 or 200 Amperes, tops.  And the TRANSFORMER on 
the pole, that supplies the whole neighborhood, is probably a 50 kw unit.  
        
             
        
        
        
That's false. Displacement would be (r2 - r1) .
 
        
             
        
        
        
B.False
Einstein's vision of GR is NOT that somehow Gravity comes along and alters (indents?) some existing structure.
It is that Gravity (with its four possible sources) actually determines the entire global structure of Space-Time in which such sources are extant.
        
             
        
        
        
Answer:
Explanation:
The mass of the car doesn't matter because On a flat curve the mass of the car does not affect the speed at which it can stay on the curve. You would need the mass if you were solving the the centripetal force acting on the car, but not the acceleration.
