The acceleration due to gravity on Earth differs slightly from place to place, depending on topography (e.g., whether you areon a hill or in a valley) and subsurface geology (whether there is dense rock like iron ore as opposed to light rock like saltbeneath you.) The precise acceleration due to gravity can be calculated from data taken in an introductory physicslaboratory course. An object, usually a metal ball for which air resistance is negligible, is dropped and the time it takes to falla known distance is measured. Very precise results can be produced with this method ifsufficient care is taken in measuring the distance fallen and the elapsed time.
The apparent weight of a rider in a vertical amusement park ride is determined by:
O the centrifugal force
the weight of the rider
O the centripetal force
the Normal force exerted on the rider
Suppose the mass of a fully loaded module in which astronauts take off from the Moon is 14,200 kg. The thrust of its engines is 25,000 N. (Assume that the gravitational acceleration on the Moon is 1.67 m/s2.)
(a) Calculate (in m/s2) its magnitude of acceleration in a vertical takeoff from the Moon.
(b)Could it lift off from Earth? If not, why not?
i.) No, the thrust of the module's engines is less than its weight on Earth.
ii.)Yes, the thrust of the module's engines is equal to its weight on Earth.
iii.)Yes, the thrust of the module's engines is greater than its weight on Earth.
iv.)No, the thrust of the module's engines is equal to its weight on Earth.
If it could, calculate (in m/s2) the magnitude of its acceleration. (If not, enter NONE.)
