On planet x, an object weighs 19.7 n. on planet b where the magnitude of the free-fall acceleration is 1.92 g (where g = 9.8 m/s^2 is the gravitational acceleration on earth), the object weighs 29.8 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 what is the free-fall acceleration on planet x? answer in units of m/s^2

Mass of object in Earth = 1.58 kg.

Free-fall acceleration on planet X = 12.47 m/s²

Explanation:

We know weight is the product of mass and acceleration due to gravity.

Mass is a constant.

           W = mg

On planet X, an object weighs 19.7 N.

On planet B where the magnitude of the free-fall acceleration is 1.92 g (where g = 9.8 m/s^2 is the gravitational acceleration on Earth), the object weighs 29.8 N.

Mass of object in Earth = 1.58 kg.

We need to find free-fall acceleration on planet X.

Free-fall acceleration on planet X = 12.47 m/s²
