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. $T_{f} = \sqrt{2}(t_{m})$

Answer 1

Answer: (A)

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

Answer 2

Time to reach maximum height $= t_{m}$

Time to reach back to ground $= t_{m}$

Total time of flight,$T_{f} = t_{m} + t_{m} = 2t_{m}$
