**acceleration due to gravity help!!**

**1. Homework Statement**

PROB: How long would it take for a mass of 1kg to fall a distance of 2m to the surface of the moon?

**2. Homework Equations**

G=6.673*10^-11 Nm^2/kg^2

R of moon = 1.76*10^6m

m of moon = 7.35*10^22kg

**3. The Attempt at a Solution**

i started by finding the acceleration due to gravity by using g= (m)(G)/r^2

(m=mass of moon, G as the gravitational constant, r= radius of moon)

finding that g is 1.58m/s^2

now i am lost in what formula to use to get the displacement of this object???
