[" There are two values of time for which a projectile "],[" is at the same height.The sum of these two "],[" times is equal to: "]

Show that there are two values of time for which is projectile is at the same height. Also show that the sum of these two times is equal to the time of flight.

Show that there are two values of time for which a projectile is at the same height. Also show mathematically that the sum of these two times is equal to the time of flight.

Show that there are two values of time for which a projectile is at the same height. Also show mathematically that the sum of these two times is equal to the time of flight.

During flight there are two instants of time when the projectile is at same height from the ground. Show that the sum of the two instants is equal to total time of flight.

For given value of u, there are two angles of projection for which the horizontal range is the same. the sum of the maximum heights for these two angles is

For given value of u, there are two angles of projection for which the horizontal range is the same. Show that the sum of the maximum heights for these two angles is independent of the angle of projection.

Two dice are thrown at a time.The probability that the sum of two numbers is equal to 5 is

Two projectiles are projected from the same point different velocities and different angles of projection .If the maximum height attained by both the projectiles is same, show that sum of the times taken by each to reach the highest point is equal to the total time of flight of either of the projectiles .
