Question

The weight of an object on Earth is 350 newtons. On Mars, the same object would weigh 134 newtons. What is the acceleration due to gravity on the surface of Mars, given that it is 9.8 meters/second2 on Earth?



0.78 meters/second2



2.74 meters/second2



3.75 meters/second2



5.78 meters/second2



9.80 meters/second2

Answer 2

The weight of an object is defined as its mass times the acceleration due to gravity. On earth, this constant is 9.8 meters/second^2. Hence, an object with weight 350 Newton has a mass of 350/9.8=35.7 kilograms. The mass of an object (its 'resistance to acceleration') does not change, so if on Mars an object weighs 134 Newton, the constant of gravity on Mars ( a ) is given by: 134/a = 35.7. It is easy to see that the acceleration due to gravity on Mars is 3.75 m/s^2.
