A) time of ascent \[\ge \] time of descent
B) time of ascent \[=\] time of descent
C) time of ascent < time of descent
D) time of ascent > time of descent
Correct Answer: B
Solution :
When a ball is thrown vertically upwards its velocity goes on decreasing due to gravitational acceleration till it becomes zero. After that it falls down with the same gravitation acceleration. Its velocity the point of projection becomes equal to the velocity of projection. Hence the time of ascent is equal to the time of descent.
