Question

Show that the upward time of flight is equal to downward time of flight for a projectile motion.

Answer 1

Total time of flight = 2u/g

Upward time of flight = u/g

Total time of flight = upward time of flight + downward time of flight

2u/g = u/g + downward time of flight

Downward time of flight = 2u/g - u/g

= u/g which is equal to upward time of flight
