Question

Mark weighs 200 Newtons on Earth, where the force of gravity is 10m/s^2. He goes to Mars, where the force of gravity 3.5 m/s^2. What is Mark's weight on Mars?
A. 70 N
B. 570 N
C. 200 N
D. 700 N

Answer 1

To find Mark's weight on Mars, we can use the formula:

Weight = Mass x Gravity

Since Mark's mass doesn't change, we can ignore it and just focus on the change in gravity.

On Earth, the force of gravity is 10 m/s^2. On Mars, the force of gravity is 3.5 m/s^2.

Weight on Mars = (Weight on Earth) x (Gravity on Mars / Gravity on Earth)

Weight on Mars = 200 N x (3.5 m/s^2 / 10 m/s^2)

Weight on Mars = 70 N

Therefore, the correct answer is:

A. 70 N
