Question

The relation between the time of flight of 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. $T_{f} =\sqrt{2}\left(t_{m}\right)$

Answer 1

Answer: (A)

Time to reach maximum height $= t_m$
Time to reach back to ground $= t_m$
Total time of flight, $T_f = t_m + t_m = 2t_m$
