An astronaut has reached the surface of a distant planet. He drops a stone from the top of a cliff on the planet and observes that it takes t 1 = √2 sec to reach the bottom. He now throws another stone vertically upwards so that it reaches a height h = 1 m above the cliff before dropping down the cliff. The second stone takes a total time t 2 = 2 sec to reach the bottom of the cliff, starting from the time it leaves the astronaut's hand. The planet has a very thin atmosphere which affers negligible air resistance. What is the value of acceleration (in m/s) due to gravity on this planet?
