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

Options

A.
B.
C.
D.

Answer

A

Explanation

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.
