On planet X, an object weighs 8.59 N. On planet B where the magnitude of the free-fall acceleration is 1.28 g (where g = 9.8 m/s 2 is the gravitational acceleration on Earth), the object weighs 18.69 N. The acceleration of gravity is 9.8 m/s 2 . What is the mass of the object be on Earth? Answer in units of kg.

Answer:

14.6kg

Explanation:

Mass is an extensive property of matter that depends on the amount of matter that is present.

Weight is the force applied by gravity on a body.

                 Weight  = mg

 m is the mass of the body

  g is the acceleration due to gravity

Given;

Weight on planet B = 18.69N

Acceleration due to gravity on B = 1.28m/s²

 So, let us find the mass from this value;

           18.69  = mass x 1.28

           mass  = 14.6kg

The mass of the body on earth is  14.6kg
