Question

Consider the given velocity-time graph. It represents the motion of -

• A. A projectile projected vertically upward from a point
• B. An electron in the hydrogen atom
• C. A car with constant acceleration along a straight road
• D. A bullet fired horizontally from the top of a tower

Answer 1

The correct option is A A projectile projected vertically upward from a point

As can be seen that velocity is decreasing with time and after reaching to 0, its magnitude starts increasing again. Hence, it is a case of an object thrown upwards with some initial velocity v${}_0$.
