Final answer:
The free fall acceleration experienced by the 0.50-kg object at the surface of planet X is 40 m/s², which is calculated by dividing the weight by the mass of the object.
Step-by-step explanation:
To find the free fall acceleration experienced by the 0.50-kg object on the surface of planet X, you can use the following formula:
Weight (W) = mass (m) × acceleration due to gravity (g)
The weight of the object on planet X is given as 20 N, and the mass (m) is 0.50 kg. Plugging these values into the formula, we get:
20 N = (0.50 kg) × g
To solve for g, divide both sides by the mass:
g = 20 N / 0.50 kg = 40 m/s²
Therefore, the free fall acceleration experienced by the 0.50-kg object at the surface of planet X is 40 m/s², which corresponds to option d.
