Question

if an astronaut weighs 148 n on the moon and 893 n on earth, then what is his mass? ____ kg use earths g = 9.81 m/s² and do not include units in your answer. enter the answer

Explanation:

Step1: Recall weight - mass formula

Weight $W = mg$, where $W$ is weight, $m$ is mass and $g$ is acceleration due to gravity.

Step2: Calculate mass using Earth - data

We know $W = 893$ N on Earth and $g = 9.81$ m/s². Rearranging the formula $m=\frac{W}{g}$. Substituting values, we get $m=\frac{893}{9.81}$.

Step3: Perform the division

$m\approx91$

Answer:

91
