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

A. `3 T//2`

B

B. `4 T//3`

C

C. `3 T//4`

D

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`.
