# Kinetic Energy Proton

Generally we say that the kinetic energy of an object is the energy possess by that system due to its motion. The positively charged particle exists inside the nucleus of an atom is nothing but a protons.When we combine the kinetic energy and the proton then it lead to the formation of the Kinetic energy proton.

What is a Kinetic Energy Proton:Kinetic energy is defined as the work needed to accelerate a body of a given mass from rest to its current velocity. The protons are the +1 elementary charge particles existing inside the nucleus of an atom. A proton is same as H+ ion.Kinetic energy may also be defined as the energy possess by an object by virtue of its motion. The proton is a subatomic particle exists inside the nucleus and have an electric charge of one positive fundamental unit and a mass of 938.3 MeV/c2, or about 1836 times the mass of an.

Examples of Kinetic Energy Proton:Question: A proton is traveling to the right at 5 × 107 m/s. It has a head-on perfectly elastic collision with a stationary boron atom. The mass of the boron atom is 4.00 times the mass of the proton. What is the speed of proton after the collision? What is the speed of the boron atom after the collision?

I am planning to write more post on Calculate Molecular Formula  and Calculate Empirical Formula . Keep checking my blog.

Answer: Before collision: Speed of proton is v1 = 5 × 107 m/sSpeed of atom is v2 = 0 m/sAfter collision: Speed of proton is v13 and Speed of atom is v4Use the conservation of momentum and the conservation of kinetic energy:p1 + p2 = p3 + p4 => m*v1 = m*v3 + 4m*v4E1 + E2 = E3 + E4 => 1/2*m*v1^2 = 1/2*m*v3^2 + 1/2*4m*v4^2Solve this for v3 and v4.I get v3 = -3/5*v1 and v4 = 2/5*v1.
