Question
A body is thrown vertically upwards. If air resistance is to be taken into account, then the time during which the body rises is
- Equal to the time of fall
- Less than the time of fall
- Greater than the time of fall
- Twice the time of fall
The correct answer is: Less than the time of fall
Let the initial velocity of ball be 
Time of rise
and height reached 
Time of fall
