Particle-x has a speed of 0.720 c and a momentum of 4.350x1019 kgm/s. what is the mass of the particle? 2.0206 10-27 kg hints: the classical momentum of an object is the product of its mass and its velocity. how does the relativistic momentum look like comp classical momentum? submit answer incorrect. tries 2/12 previous tries what is the rest energy of the particle? submit answer tries 0/12 what is the kinetic energy of the particle? submit answer tries 0/12 what is the total energy of the particle?

Explanation:

Given that,

Speed of particle = 0.720 c

Momentum = 4.350\times10^{-19}\ kgm/s[/tex]

(I). We need to calculate the mass of the particle

Using formula of momentum

We need to calculate the rest mass of particle

Using formula of rest mass

Where, = rest mass

Put the value into the formula

(b). We need to calculate the rest energy of the particle

Using formula of energy

Put the value into the formula

(c).  We need to calculate the kinetic energy of the particle

Using formula of kinetic energy

(d). We need to calculate the total energy of the particle

Using formula of energy

Put the value into the formula

Hence, This is the required solution.
