The sun is a star (a giant ball of burning gases).
Newton's second law of motion pertains to the behavior of objects for which all existing forces are not balanced. The second law states that the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object. The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object. As the force acting upon an object is increased, the acceleration of the object is increased. As the mass of an object is increased, the acceleration of the object is decreased.
The characteristics of the projectile launch allows to find the result for the velocity on the x axis is:
- In the horizontal axis there is no acceleration and therefore the speed must be kept constant.
- The horizontal speed is vₓ = 8.0 m / s
In projectile launching we have an application of kinematics to motion in two dimensions near the surface of the Earth.
In this case, on the vertical axis we have an acceleration directed towards the center of the planet and called the gravity acceleration.
In the horizontal axis or x axis there is not acceleration, except in special cases that we tone is how much the resistance of the air.
Consequently in the horizontal axis there is no acceleration and therefore the speed must be kept constant, the result for the horizontal speed is:
vₓ = 8.0 m / s

Answer:
In fission, energy is gained by splitting apart heavy atoms, for example uranium, into smaller atoms such as iodine, caesium, strontium, xenon and barium, to name just a few. However, fusion is combining light atoms, for example two hydrogen isotopes, deuterium and tritium, to form the heavier helium.
