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
570 N
b
200 N
c
70 N
d
700 N
To find Mark's weight on Mars, we can use the formula:
Weight = mass * gravity
Mark's weight on Earth is 200 Newtons and the force of gravity on Earth is 10 m/s^2. Plugging these values into the formula, we get:
200 = mass * 10
Solving for mass:
mass = 200 / 10 = 20 kg
Now, let's calculate Mark's weight on Mars. The force of gravity on Mars is 3.5 m/s^2. Plugging in the values:
Weight = mass * gravity = 20 * 3.5 = 70 Newtons
Therefore, Mark's weight on Mars is 70 Newtons. The answer is c) 70 N.
