The diagram above shows a velocity – time graph. The statement that is true about this motion is that the car
-
A.
has no acceleration between point F and G -
B.
decelerates between F and H -
C.
has a constant soeed between points E and F -
D.
Accelerates between points F and G
Correct Answer: Option 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
