The mean distance of a moon from a planet is 2.82 times 10 superscript 5 miles. assuming that the orbit of the moon around the planet is circular and that 1 revolution takes 21.6 days (1 day is 22 hours), find the linear speed of the moon. express your answer in miles per hour.

linear speed = 595.706 miles/hours

Explanation:

to find the linear speed of the moon (Express your answer in miles per hour)

Given

radius of the moon = 1737.1 km = 1079.4 mile (a constant value)

The mean distance of a moon from a planet is 2.82 * 10^ 5 miles

therefore, the total distance from the moon to the planet =

=1079.4 + 2.82 * 10^ 5 = 283,079.4 miles

Assuming that the orbit of the moon around the planet is circular and that

1 revolution takes 21.6 days = 21.6*22hours =  475.2 hours

(1 day is 22 hours),

therefore, the time taken for the moon to move round the planet is = 475.2 hours

then,

linear speed = Distance/time

                     =283,079.4 miles /475.2 hours = 595.706 miles/hours

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.

it is a negative acceleration
