If a metal ball of mass 45kg is released at a height of 50m with acceleration due to gravity of 1.66m/s^2 then how much time will it take to reach the ground

According to newton’s law of universal gravitation, which statements are true? as we move to higher altitudes, the force of gravity on us decreases. as we move to higher altitudes, the force of gravity on us increases. as we gain mass, the force of gravity on us decreases. as we gain mass, the force of gravity on us increases. as we move faster, the force of gravity on us increases.
