Question

How much would a $70 \mathrm{~kg}$ man weigh on the moon? What would be his mass on the earth and on the moon? (Acceleration due to gravity on $\mathrm{moon}=1.63 \mathrm{~m} / \mathrm{s}^{2}$ )

Answer 1

Solution. 

We will first calculate the weight of the man on the moon.

Here, Mass of the man on moon, $m=70 \mathrm{~kg}$

Acceleration due to gravity, $8=1.63 \mathrm{~m} / \mathrm{s}^{2}$

(on the moon)

We know that: $\quad W=m \times 8$

So, $\quad W=70 \times 1.63$

$W=114.1 \mathrm{~N}$

Thus, the man would weight 114.1 newton on the moon.
