An object has a mass of 300 g. (a) What is its weight on Earth? (b) What is its mass on the Moon? (c) What will be its acceleration on the Moon when a 0.500 N resultant force acts on it?
(a) The weighi of the object is:
where is its mass and is the gravitational acceleration. Thus:
(b) The mass of any object on the Moon is the same as on Earth. In this case 300 g.
(c) The acceleration can be calculated using the Newton's second law:
where is the resultant force. Thus, obtain:
Answer. a) 2.943 N, b) 300 g, c)1.67 m/s^2.
