The velocity – time graph of a moving body is shown in the figure. Which of the following statements is true?
(1) The acceleration is constant and positive.
(2) The acceleration is constant and negative.
(3) The acceleration is increased and positive.
(4) The acceleration is decreasing and negative.
(3) The acceleration is increased and positive.
As slope of v–t gives acceleration and slope is positive as well as increasing.
option 3 will be correct
