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.

A

`3 T//2`

B

`4 T//3`

C

`3 T//4`

D

T

Text Solution

Verified by Experts

The correct Answer is:
D
(d) `t_(OA) = t_(BC)`
To find `t_(OA) + t_(OB)`,
`t_(OA) + t_(OB) = t_(BC) + (t_(OB)) = T`.

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.

There are two values of time for which a projectile is at the same height. The sum of these two times is equal to (T = time of flight of the projectile)

Define time of flight for a projectile .

The time of flight of the projectile is:

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 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 .

Two projectiles are thrown with different velocities and at different angles so as to cover the same maximum height. Show that the sum of the times taken by each to reach the highest point is equal to the total time taken by either of the projectiles.

Show that the horizontal range of a projectile is same for two angles of projection . Is the sum of maximum heights for these two angles dependent on the angle of projectile ?

" For a projectile the ratio of the square of the time of flight to its maximum height is "

If the time of flight of a projectile is doubled, what happens to the maximum height at tained?
