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
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
