Imagine that a space probe could be fired as a projectile from the earth's surface with an initial speed of 5.52 104 m/s relative to the sun. what would its speed be when it is very far from the earth (in m/s)? ignore atmospheric friction, the effects of other planets, and the rotation of the earth. (consider the mass of the sun in your calculations.)

Explanation:

As per energy conservation we can say

initial total energy of the object at the surface of earth = final total energy of the object at highest height

now we have

here we know that

M = mass of earth

m = mass of object

R = radius of earth

now when object reached far away from the earth then it will only have kinetic energy

now by energy conservation

the device is called “ rocket engine”

a lot of it means it can be "burned" for energy and sold at one price. if it is scarce, the price will go up
