If the man and woman are taken to a planet where the acceleration due to gravity is twice that of earth repeat the woman mass was 25kg on earth and the man was 300N on another planet

If The Man And Woman Are Taken To A Planet Where The Acceleration Due To Gravity Is Twice That Of Earth Repeat The Woman Mass Was 25kg On Earth And The Man Was class=

Sagot :

The mass of the woman is 25 kg because the mass is constant.

The mass of the man can be found using the formula: W = mg, where g is double Earth's gravity.

[tex]\begin{gathered} m=\frac{W}{g} \\ m=\frac{300N}{2\cdot9.8\cdot\frac{m}{s^2}} \\ m=\frac{300}{19.6}kg \\ m\approx15.3\operatorname{kg} \end{gathered}[/tex]

The mass of the man is 15.3 kg.

The weight of the man on Earth can be found with the same formula but using Earth's gravity.

[tex]\begin{gathered} W=15.3\operatorname{kg}\cdot9.8\cdot\frac{m}{s^2} \\ W=149.94N \end{gathered}[/tex]

The weight of the man on Earth is 149.94 N.

At last, the weight of the woman on Earth can be found using the same method before.

[tex]\begin{gathered} W=25\operatorname{kg}\cdot9.8\cdot\frac{m}{s^2} \\ W=245N \end{gathered}[/tex]

The weight of the woman on Earth is 245N.
