Two cannoballs A and B are fired at same angle and with same velocity from a cannon . If mass of A lt mass of B, which ball will reach the ground first ? What if the balls are fired with diferent velocities but same angle of projection?

Two cannoballs A and B are fired at same angle and with same velocity

1.	Two cannoballs A and B are fired at same angle and with same velocity from a cannon . If mass of A lt mass of B, which ball will reach the ground first ? What if the balls are fired with diferent velocities but same angle of projection?
Answer» SOLUTION :Time of flight of a projectileis directlyproportional to the initial velocity of projection . So, the BALL which is fired with lesservelocity will reach the GROUND earlier.
