Calculate the speed of a proton having a kinetic energy of 0.995 * 10-19 J and a mass of 1.673 * 10-27 kg. Answer in units of m/s.

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
