An object is dropped from rest into a pit and accelerates due to gravity at roughly 10m/s^2. It hits the ground in 5 seconds. A rock is then dropped from rest into a second pit and hits the ground in ten seconds.How much deeper is the second pit. no air resistance.

2. Relevant equations

not used

3. The attempt at a solution

im pretty sure the answer is 4 times.

but im not 100%. is it sorta like braking from one velocity to stop then a second(half as much) to stop and finding the distance it takes to stop.because thats four times as long.
