Final answer:

The mass of the rock is 1228.9 kg.

Step-by-step explanation:

To find the mass of the rock, we can use the formula:

Weight = mass × gravitational field strength

Given that the gravitational field strength on the moon is 1.63 N/kg and the weight of the rock is 2000 N, we can substitute these values into the formula:

2000 N = mass × 1.63 N/kg

Solving for mass, we get:

mass = 2000 N / 1.63 N/kg = 1228.9 kg

Therefore, the mass of the rock is 1228.9 kg.
