The diagram above shows a velocity – time graph. The statement that is true about this motion is that the car?
-
has no acceleration between point F and G
- decelerates between F and H
- has a constant soeed between points E and F
- Accelerates between points F and G
The correct answer is: A
Explanation
Above are the V-t graphs for
I Uniform acceleration
II uniform retardation
III Uniform velocity
Thus the car has no acceleration between point F and G since that portion of the graph represents uniform velocity
There is an explanation video available .
