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

that tool is called an altimeter which measures your altitude which can be used to tell which atmosphere you are currently in, including the stratosphere.

hope this ! : )

the only real purpose of sputnik 1 was to beat the us into space. we were getting close to launching a useful satellite, explorer 1 - which launched on january 31, 1958. the ussr had to beat that, so they launched sputnik 1 on october 4, 19
