# An astronaut with mass \( 75 \) \( \text{kg} \) travels to Mars. Determine his weight under the following conditions.

An astronaut with mass \( 75 \) \( \text{kg} \) travels to Mars. Determine his weight under the following conditions.

**Part a)** On Earth, find the astronaut’s weight. *(3 points)*

**Part b)** On Mars where \( g = 3.8 \) \( \text{m/s}^2 \), find the astronaut’s weight. *(3 points)*

**Part c)** The astronaut weighs \( 683 \) \( \text{N} \) on top of a mountain. Determine the local value of \( g \) there. *(3 points)*
