Question

On Mars, where air resistance is negligible, an astronaut drops a rock from a cliff and notes that the rock falls about d meters during the first t seconds of its fall. Assuming the rock does not hit the ground first, how far will it fall during the first 4t seconds of its fall?

Answer 1

I think this question is missing information about the grav accn on mars

Then it would be

distance = 1/2 x mars acceleration x (4t)squared
