The weight of an object is mg. If m = 60 kg and g = 9.8 m/s^2, what is its weight in newtons?

Explanation:
Weight is the gravitational force on a mass, found by multiplying its mass by the acceleration due to gravity: W = m g. With m = 60 kg and g = 9.8 m/s^2, W = 60 × 9.8 = 588 N. The unit newton comes from kg·m/s^2, confirming the result in newtons. The other options don’t fit because they would require a different g or mass (for example, 600 N uses g ≈ 10, and 9.8 N would be the weight of a 1 kg mass).
