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

1 answer

To find the weight of Mark on Mars, we need to multiply his mass by the force of gravity on Mars.

Using the equation weight = mass * gravity, we have:

Weight on Mars = Mass * Gravity on Mars

Given that Mark weighs 200 Newtons on Earth, we can determine his mass by dividing his weight by the force of gravity on Earth:

Mass = Weight on Earth / Gravity on Earth = 200N / 10 m/s^2 = 20 kg

Now, we can calculate Mark's weight on Mars using his mass and the force of gravity on Mars:

Weight on Mars = Mass * Gravity on Mars = 20 kg * 3.5 m/s^2 = 70 N

Therefore, Mark's weight on Mars is 70 Newtons. Answer choice A.
