Compare the circular velocities of the satellites and/or moons of Mars and Earth, using Reasoning with Number 4-1 as your guide. Which has the higher velocity and by how much?
What will be an ideal response?
Use information in Appendix A to find distances to satellites of Mars and mass of Mars and the circular velocity formula.
Example calculation:
Mars-Deimos distance = 23,400 km
Mars-Phobos distance = 9400 km
Mars mass = 6.39 × 1023 kg

To determine the location of the center of mass of a car, the car is driven over a scale. When the front wheels are over the scale, the weight recorded by the scale is 5800 N, and when the rear wheels are over the scale, the scale reads 6500 N
The distance between the front and rear wheels is 3.20 m. How far behind the front wheels is the center of mass located? A) 0.845 m B) 1.50 m C) 1.59 m D) 1.69 m E) 1.72 m
