Chapter 3.1, Problem 3PP

To determine

The gravitational strength on Mars.

Answer to Problem 3PP

The gravitational strength on Mars is $3.7\text{N/kg}$ .

Explanation of Solution

Given info:

Mass of astronaut, $m=100\text{kg}$

Weightof astronaut, $F_g=370\text{N}$

Formula used:

The formula for the gravitational strength is given by,

  $g=\frac{F_g}{m}$

Calculation:

Write the expression to calculate the gravitational strength.

  $g=\frac{F_g}{m}$

Here,

• $m$ is mass of the astronaut.
• $g$ is the gravitational constant.

Substitute the given values in the above equation.

  $\begin{array}{c}g=\frac{F_g}{m}\\ =\frac{370}{100}\\ =3.7\text{N/kg}\end{array}$

Conclusion:

Hence, thegravitational strength on Marsis $3.7\text{N/kg}$ .
