Question

Calculate the kinetic energy in J of an electron moving at 6.00 x 10^6 m/s. The mass of an electron is

9.11 x 10^-28 g.

Answer 1

The kinetic energy of an electron moving at 6.00 x 10^6 m/s is approximately 1.097 x 10^-14 J.

Step-by-step explanation:

The kinetic energy of an electron can be calculated using the equation:

Kinetic Energy (KE) = 0.5 * mass * velocity^2

Converting the electron's mass from grams to kilograms, we get:

Mass = 9.11 x 10^-28 g = 9.11 x 10^-31 kg

Substituting the values into the equation:

KE = 0.5 * (9.11 x 10^-31 kg) * (6.00 x 10^6 m/s)^2

Calculating this, we find that the kinetic energy of the electron is approximately 1.097 x 10^-14 J.
