Question

Will air resistance hamper the equality of times of ascent and descent
in a projectile?
​

Answer 1

Air resistance will act against the direction of motion, so it will be vertically downwards during ascent and vertically upwards during descent. Hence the net force ( gravity plus air resistance) will be more during ascent and less during descent. Hence time of travel will be less while going up.
