The escape velocity is defined to be the minimum speed with which an object of mass m must move to escape from the gravitational attraction of a much larger body, such as a planet of total mass m. the escape velocity is a function of the distance of the object from the center of the planet r, but unless otherwise specified this distance is taken to be the radius of the planet because it addresses the question "how fast does my rocket have to go to escape from the surface of the planet? "

Explanation:

Taking into account what is stated in this problem and considering there is no friction during the takeoff of the rocket of the planet, the rocket will escape the gravitational attraction of the massive body when its kinetic energy and its potential energy are equal in magnitude.

Written mathematically is:

 (1)

Where:

(2)

Being the mass of the rocket

And:

  (3)

Being   the mass of the planet,   the gravitational constant and   the radius of the planet.

Substituting (2) and (3) in (1):

(4)

Finding , which is the escape velocity:

 this is the velocity the rocket must have in order to escape from the surface of the planet

the answer is a. the yacht traveled from the dock north to the 200-meter marker in the bay in less than 5 minutes, giving the passengers several more hours to fish.

im doing peak rn so sry if its wrong

this is an example of "committed" time.

committed time, as contracted time, takes need over essential and available time since it is seen as profitable work. it alludes to the time allotted to keep up a home and family. at the point when a man is commuting using committed time this individual may feel that the drive is an obligation to family, for example, strolling youngsters to class or driving a mate to work. contracted and committed time clients may feel that their commute could really compare to the commute of important or leisure time clients on the grounds that their commute is profitable work. in this manner, they might be more disposed to pick a mechanized method of movement.
