Question

Calculate the kinetic energy of a particle with a mass of 3.334 x 10-27 kg and a speed of 2.89 x 105 m/s

Answer 1

Kinetic Energy of the particle is given by

$KE = \frac{1}{2}mv^2$

$KE = \frac{1}{2}*3.334*10^{-27}*(2.89*10^5)^2$

$KE =1.392*10^{-16} J$

So above is the kinetic energy for the given mass.
