Answer:
1.19×10²² m/s
Explanation:
Kinetic Energy: This can be defined as the the energy of a body due to motion.
The formula for kinetic energy is given as,
Ek = 1/2mv²................... Equation 1
Where Ek = Kinetic energy, m = mass of proton. v = velocity of proton.
Making v the subject of the equation,
v = √(2Ek/m).................. Equation 2.
Given: Ek = 0.995×10⁻⁵ J, m = 1.673×10⁻²⁷ kg.
Substitute into equation 2
v = √(2×0.995×10⁻⁵/1.673×10⁻²⁷ )
v = 1.19×10²² m/s.
Therefore, the velocity of proton = 1.19×10²² m/s
