Question
I step foot on an alien planet that is completely void ofatmosphere. My astronaut companions failed to brief me on the size of theplanet, and I want to experimentally determine this size on myown. I remove a wrench from the outside storage compartment of mypressurized suit and drop it from precisely 1.500 meters above theground. A computer in my space suit informs me that the wrench struckthe ground exactly 0.200 seconds after I released it. --------------- (A) What is theacceleration due to gravity on this planet? IF there is enough information todetermine, then what is: (B1) The massof the planet. (B2) The radiusof the planet. I step foot on an alien planet that is completely void ofatmosphere.

You have a good handle on this questionalready, I like to think OUTSIDE THE BOX. Would it help to know the relative radiusand mass of all the planets in our system, then you could choose the closest and makea guess?Mercury .38 .05 Venus .95 .89 Earth 1 1 Mars 0.53 .11 Jupiter 11 318 Saturn 9 95 Uranus 4 17 Neptune 4 17 Pluto .18 .002 Would it help to know the relative radiusand mass of all the planets in our system, then you could choose the closest and makea guess?
Mercury .38 .05 Venus .95 .89 Earth 1 1 Mars 0.53 .11 Jupiter 11 318 Saturn 9 95 Uranus 4 17 Neptune 4 17 Pluto .18 .002 then you could choose the closest and makea guess?
