A resistance to change in motion describes inertia.

Inertia is the resistance of any physical object to any change in its state of motion (this includes changes to its speed, direction or state of rest). It is the tendency of objects to keep moving in a straight line at constant velocity.

The correct answer between all the choices given is the last choice. I am hoping that this answer has satisfied your query and it will be able to help you in your endeavor, and if you would like, feel free to ask another question.

The satellite s travels around the earth in a circular path with a constant speed of 20 mm>h. If the acceleration is 2.5 m&gt

Answer:

The altitude of planet = 5989.198 km

Explanation:

We know that centripetal acceleration, $a = v^2/r$ , where v is the velocity and r is the radius. In this case both acceleration and velocity is given, so we can find radius of satellite.

v = $20 Mm/hr = 20*10^6/3600 = 5555.56 m/s$

a = $2.5 m/s^2$

So, $2.5 = 5555.56^2/r\\ \\ r = 12345698.77 m = 12345.698km$

We have diameter of earth = 12713 km

Radius of earth = 12713/2 = 6356.5 km

The altitude of planet = Radius of planet - radius of earth

= 12345.698 - 6356.5

= 5989.198 km
