Answer:
Nothing is more important to us on Earth than the Sun. Without the Sun's heat and light, the Earth would be a lifeless ball of ice-coated rock. The Sun warms our seas, stirs our atmosphere, generates our weather patterns, and gives energy to the growing green plants that provide the food and oxygen for life on Earth.
Explanation:
In this three body system total kinetic energy remains constant:


If we assume that upwards movement is positive and downwards movement is negative the formula is:

Formula for kinetic energy is:

Now we have:

We got two solutions: positive and negative. The speed is 5.04 m/s and direction can be upwards and downwards.
