What is the original height of the rock

Reference no: EM13556603

A rock is dropped from rest at earth surface (g=9.80m/s^2)and reaches the ground in 1.80s. when droped from the same height on mars it takes 3.12 seconds to reach the ground

1) what is the original height of the rock?

2) what is the gravitational acceleration on the surface of mars?
