an object of 3 kg is dropped from 2m above the ground. it takes a time interval of tE to reach the ground of the earth. if it is dropped on the moon, how long does it take to reach the ground? the a dure to g on the moon is 1/6 of that on the earth.

h= 1/2 g t^2
t= sqrt(2h/g)

so, if g is 1/6, it will take sqrt(6) times longer.
