On Mars, Mark's weight would be less than on Earth because the force of gravity on Mars is lower.
To find Mark's weight on Mars, we can use the formula:
Weight = Mass x Gravity
Since Mark's mass doesn't change when he goes to Mars, we can say:
Weight on Earth / Gravity on Earth = Weight on Mars / Gravity on Mars
Substituting the given values:
200 N / 10 m/s^2 = Weight on Mars / 3.5 m/s^2
Simplifying the equation:
20 = Weight on Mars / 3.5
To solve for Weight on Mars, we can cross multiply:
Weight on Mars = 20 x 3.5 = 70 N
Therefore, Mark's weight on Mars would be 70 N.
The answer is b. 70 N
Mark weighs 200 Newtons on Earth, where the force of gravity is 10 m/s2. He goes to Mars, where the force of gravity is 3.5 m/s2. What is Mark's weight on Mars?
a. 200 N
b. 70 N
c. 700 N
