What is the acceleration due to gravity on planet X?

An object near the surface of planet X falls freely from rest and reaches a speed of 19.3 meters per second after it has fallen 14.4 meters. do you know about it?

The acceleration due to gravity on Earth is 9.81m/s2(squared) based on the rotation of the earth round its Axis.

I haven't been on Planet X yet so I can't answer your question :lol:

v^2-u^2=2as
19.3^2-0=2x a x14.4
a=372.49/28.8
a=12.934m/s^2

I have absolutely no idea how you got it, and I don't want to know, but I am impressed :flop:
