A body is thrown vertically upwards. Which one of the following graphs correctly represent the velocity vs time?

Answer : Kinematics mcq option image

Solution :
For a body thrown vertically upwards acceleration remains constant ($$a =- g$$ ) and velocity at anytime $$t$$ is given by $$V=u- gt$$
During rise velocity decreases linearly and during fall velocity increases linearly and direction is opposite to each other.
Hence graph (A) correctly depicts velocity versus time.
