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
Penjelasan
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
