Physics

An astronaut shipwrecked on a distant planet is on top of asheer vertical cliff (let’s call it point P), which he wishessomehow to climb down. He does not know the acceleration due togravity on the planet, and he has only a good watch with which tomake measurements. He wants to learn the height of the cliff (fromP down to the bottom). To do this,he makes two measurements. 1) Hedrops a rock fall from rest off the cliff edge (from point P) andfinds that the rock takes 4.15 s to reach the bottom. 2) He tossesanother rock straight upward from P such that it rises a height ofwhat he estimates to be 2 m (up from P) before it falls to theground below. This time the rock takes 6.30 s from the originaltoss to hit the bottom. What is the height of the cliff (point Pdown to the bottom below)?
