When interplanetary space travel becomes viable, doctors may suggest to people with arthritis that they vacation on a planet with lower gravitational attraction and do more walking. The gravitational acceleration on Earth is 9.8 m/s2 , while the gravitational acceleration on Mars is 3.7 m/s2 . How much less force would the vacationer be applying to their joints when walking on Mars? (1 point) Responses 36.26 times less force 36.26 times less force 2.6 times less force 2.6 times less force 13.5 times less force 13.5 times less force 6.1 times less force
The force applied to a person's joints when walking can be calculated using the formula F = m * g, where F is the force, m is the mass of the person, and g is the gravitational acceleration.
Let's assume the mass of the person is 70 kg.
On Earth: F = 70 kg * 9.8 m/s^2 = 686 N
On Mars: F = 70 kg * 3.7 m/s^2 = 259 N
Therefore, the force applied to the joints on Mars is 2.65 times less than on Earth.
So, the correct answer is 2.6 times less force.
