A) On planet X, an object weighs 19.2 N. On planet B where the magnitude of the free-fall acceleration is 1.17 g (where g = 9.8 m/s2 is the gravitational acceleration on Earth), the object weighs 34.9 N.

The acceleration of gravity is 9.8 m/s2 . What is the mass of the object be on Earth? Answer in units of kg

B) What is the free-fall acceleration on planet X? Answer in units of m/s2

A. M*1.17g = 34.9 N.
M*1.17*9.8 = 34.9
M*11.47 = 34.9
M = 3.04 kg

B. 3.04 * a = 19.2 N.
a = 6.31 m/s^2 on planet X.

Note: It is the free-fall acceleration
that changes; the mass remains constant.
