On planet #3, you fire a projectile horizontally from the edge of a vertical cliff 34.4 m above the ground, with an initial speed of 72.6 m/s. The projectile lands 63.5 m away from the base of the cliff. What is the value of g for planet #3?

282.83 m/s^2 |

28.51 m/s^2 |
option #1 is correct.
There will be force in horizontal direction thus velocity in x direction will be constant, while velocity in y direction will keep on increasing because of acceleration due to gravity.
