Proponents of astrology claim that the positions of the planets at the time of a baby's birth will affect the life of that person in important ways. Some assert that this effect is due to gravity. Examine this claim with Newton's law of gravity. Calculate the maximum force exerted on the baby by the planet Mars and compare that with the force of gravity exerted by the mass of the doctor's head as she delivers the baby. Assume Mars is at its closest approach to Earth at the time. You will need to estimate the mass of a newborn, as well as the mass and distance between the doctor's head and the baby.


1) Determine the distance from the Earth to Mars in meters

2) Calculate the maximum force exerted on the baby by the mass of the doctor's head as she delivers the baby.

3) Calculate the maximum force exerted on the baby by the planet Mars.
