Question

1. nasa has decided to send astronauts back to the moon. two astronauts have been selected for the program. the mass of one astronaut is 75 kg and the mass of the other is 80 kg. gravity on the moon has an acceleration of 1.62 m/s². what is the combined weight of the astronauts?

Explanation:

Step1: Calculate total mass

$\text{Total mass} = 75\ \text{kg} + 80\ \text{kg} = 155\ \text{kg}$

Step2: Calculate combined weight

$\text{Weight} = m \times g = 155\ \text{kg} \times 1.62\ \text{m/s}^2$

Answer:

$251.1\ \text{N}$
