Question

The relation between the time of flight of projectile Tf and the time to reach the maximum height tm is (A) Tf =2tm (B) Tf =tm (C) Tf =(tm/2) (D) Tf =√2(tm)

Time to reach maximum height = tm Time to reach back to ground = tm Total time of flight, Tf = tm + tm = 2tm

Q. The relation between the time of flight of projectile $T_{f}$ and the time to reach the maximum height $t_{m}$ is

$T_{f} = 2 t_{m}$

$T_{f} = t_{m}$

$T_{f} = \frac{t _{m}}{2}$

$T_{f} = 2 (t_{m})$

Time to reach maximum height $= t_{m}$
Time to reach back to ground $= t_{m}$
Total time of flight, $T_{f} = t_{m} + t_{m} = 2 t_{m}$

Q. The relation between the time of flight of projectile Tf​ and the time to reach the maximum height tm​ is

Tf​=2tm​

Tf​=tm​

Tf​=2tm​​

Tf​=2​(tm​)
