Q. The relation between the time of flight of a projectile $T_{f}$ and the time to reach the maximum height $t_{m}$ is
A) $T_{f} = 2t_{m}$
B) $T_{f} = t_{m}$
C) $T_{f} = \frac{t_{m}}{2}$
D) $T_{f} = \sqrt{2}{(t}_{m})$
Explanation
(a) Time to reach max. height $= t_{m}$
Time to reach back to ground $= t_{m}$
Total time of flight $T_{f} = t_{m} + t_{m}$
$T_{f} = 2t_{m}$
