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)Estimate the distance from the newborn to the doctor's head. in meters

2) Approximate the mass of an average newborn baby. in kg.

3) Approximate the mass of the doctor's head in kg.

4). Determine the distance from the Earth to Mars. in meters

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

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

PLEASE HELP, I AM REALLY LOST!!

1) 0.5 meters

2) Babies weigh about 8 lbs. 1 lb. = 0.04536 kg.

thank you ms. sue

I never took physics -- and it's been 60 years since I took a math class -- but common sense makes these two answers obvious!

Sure, I can help you with that! Let's break down each step to calculate the forces involved. Remember, these calculations are purely hypothetical and not intended to support the claims of astrology.

1) Estimate the distance from the newborn to the doctor's head:
The distance between the newborn and the doctor's head can vary depending on the specific scenario, but let's assume it is around 30 centimeters or 0.3 meters.

2) Approximate the mass of an average newborn baby:
The average mass of a newborn baby is about 3.5 kilograms or 3500 grams, which is equivalent to 3.5 kg.

3) Approximate the mass of the doctor's head:
This depends on the specific person, but for the sake of calculation, let's assume the mass of the doctor's head is about 5 kilograms or 5000 grams, which is equivalent to 5 kg.

4) Determine the distance from the Earth to Mars:
The distance between Earth and Mars can vary significantly due to their elliptical orbits. On average, the distance is about 225 million kilometers or 225,000,000,000 meters. However, you mentioned that we should consider Mars at its closest approach to Earth. The closest approach ever recorded is about 55.6 million kilometers or 55,600,000,000 meters.

5) Calculate the maximum force exerted on the baby by the mass of the doctor's head:
To calculate the force, we can use Newton's law of gravity, which states that the force between two objects is proportional to the product of their masses and inversely proportional to the square of the distance between them.

F = (G * m1 * m2) / r^2,

where F is the force, G is the gravitational constant (approximately 6.67430 × 10^-11 m^3 ⋅ kg^−1 ⋅ s^−2), m1 and m2 are the masses of the objects, and r is the distance between them.

Using the given values:
m1 (baby's mass) = 3.5 kg,
m2 (doctor's head mass) = 5 kg,
r (distance between baby and doctor's head) = 0.3 m.

Plugging in these values, we can calculate the force exerted by the doctor's head on the baby.

6) Calculate the maximum force exerted on the baby by the planet Mars:
Similarly, we can use Newton's law of gravity to calculate the force exerted by Mars on the baby. However, since you mentioned considering Mars at its closest approach, we will use that distance and the mass of Mars.

The mass of Mars is approximately 6.39 x 10^23 kg.

Plugging in the values:
m1 (baby's mass) = 3.5 kg,
m2 (Mars' mass) = 6.39 x 10^23 kg,
r (distance between Earth and Mars during closest approach) = 55,600,000,000 meters.

Using the values above, we can calculate the force exerted by Mars on the baby.

Remember, these calculations are purely hypothetical and do not reflect the validity of astrology.

i still don't understand it.
