Question

A ball is thrown vertically upwards. Which of the following graph/graphs represent velocity-time graph of the ball during its flight? (air resistance is neglected)

Easy
Solution

In the positive region the velocity decreases linearly (during rise) and in the negative region velocity increases linearly (during fall) and the direction is opposite to each other during during rise and fall, hence fall is shown in the negative region.
