Question

The total energy of a satellite is – 800 J. Find the values for its kinetic energy and potential energy.

Answer 1

Answer:

The kinetic energy of a satellite is half the gravitational energy, given by, If the gravitational energy is GMm/r, then kinetic energy is GMm/2r and this kinetic energy is positive.

Explanation:

How do you find kinetic energy in joules?

Image result for The total energy of a satellite is – 800 J. Find the values for its kinetic energy and potential energy.

In classical mechanics, kinetic energy (KE) is equal to half of an object's mass (1/2*m) multiplied by the velocity squared. For example, if a an object with a mass of 10 kg (m = 10 kg) is moving at a velocity of 5 meters per second (v = 5 m/s), the kinetic energy is equal to 125 Joules, or (1/2 * 10 kg) * 5 m/s2.
