| **To determine the acceleration of gravity on the Moon, it is necessary to measure a) initial and final velocities b) altitude and fall time c) initial speed d) fall time e) fall height**

b) altitude and fall time

For uniformly accelerated motion, the following formulas are valid: g = (V -Vo) / t,

h = Vo * t + g * t ^ 2/2.

h = (V ^ 2 – Vo ^ 2) / 2 * g.

where g is the acceleration of gravity, Vo is the initial speed, V is the final speed, t is the time during which the speed has changed.

If the initial velocity Vo = 0, then the formulas will look like: g = V / t,

h = g * t ^ 2/2.

h = V ^ 2/2 * g.

Then, we express g = 2 * h / t ^ 2 (from formula 2) and g = V ^ 2/2 * h (from formula 3).
