Question

an astronaut with a mass of 85 kg wears a space suit with a mass of 35 kg. if the astronaut walks on the moon at a rate of 3.2 m/s east. what is the magnitude of the momentum of the astronaut and his space suit in kg-m/s?

Answer 1

The total momentum of the astronaut and their space suit walking on the Moon at 3.2 m/s east is 384 kg-m/s.

Step-by-step explanation:

When the astronaut with a mass of 85 kg and a space suit with a mass of 35 kg walks on the Moon at a rate of 3.2 m/s east, their combined mass is 85 kg + 35 kg = 120 kg. The momentum of an object can be calculated by the formula momentum (p) = mass (m) × velocity (v). In this case, the momentum of the astronaut and space suit is p = 120 kg × 3.2 m/s, which equals 384 kg-m/s.
