Kepler derived his three laws of planetary motion entirely from
observations of the planets and their motions in the sky.

Newton published his law of universal gravitation almost a hundred
years later.  Using some calculus and some analytic geometry, which
any serious sophomore in an engineering college should be able to do,
it can be shown that IF Newton's law of gravitation is correct, then it MUST
lead to Kepler's laws.  Gravity, as Newton described it, must make the planets
in their orbits behave exactly as they do.

This demonstration is a tremendous boost for the work of both Kepler
and Newton.

<h3><u>Answer;</u></h3>

b. can be used to derive Kepler’s third law of planetary motion.

Newton’s law of universal gravitation <u><em>can be used to derive Kepler’s third law of planetary motion</em></u>.

<h3><u>Explanation</u>;</h3>

<u><em>Kepler's</em></u> three laws of planetary motion states that;

  • <em><u>All planets move about the Sun in elliptical orbits, having the Sun as one of the foci. </u></em>
  • <em><u>A radius vector joining any planet to the Sun sweeps out equal areas in equal lengths of time.</u></em>
  • <em><u>The squares of the sidereal periods of the planets are directly proportional to the cubes of their mean distances from the Sun</u></em>

<em><u>Newton's law of universal gravitation</u></em><em><u> states that every particle attracts every other particle in the universe with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.</u></em>

<u><em>Newton’s law of universal gravitation can be used to derive Kepler’s third law of planetary motion.</em></u>

The nine ring wraiths want to fly from barad-dur to rivendell. rivendell is directly north of barad-dur. the dark tower reports
Katarina [22]
The west constituent of their sequence needs to cancel out 58 mph crosswind. Subsequently a northwest direction is a 45-degree angle up to even with the destination. That is the third point out of the triangle and the right angle is at the destination. The top side is the west constituent of their flight the vertical side is their resultant travel and the hypotenuse is their definite distance flown. Since the 58 mph crosswind was negated by flying northwest, the distance from the beginning to the destination must be the same distance as the west component of their travel. The hypotenuse is square root of twice the side since it has 2 identical sides.

c = sqrt (58^2 + 58^2) = sqrt (6728) = 82.02 
 
Alternative solution:

c = sqrt (2) * 58 = 1.414 * 58 = 82.02

Therefore, they have to fly 82.02 mph
