Mr. Mabis so excited to write one of the weekly vocabulary words on the board that he runs to the board at a Speed of 10 m/s. If he has a mass of 55 kg, how much kinetic energy would he have when he crashed into the overhead cart on the way to the board?

Answer 1

To calculate the kinetic energy, we can use the formula:

Kinetic Energy = 1/2 * mass * velocity^2

Given:
Mass (m) = 55 kg
Velocity (v) = 10 m/s

Substituting the values into the formula:

Kinetic Energy = 1/2 * 55 kg * (10 m/s)^2

Simplifying:

Kinetic Energy = 1/2 * 55 kg * 100 m^2/s^2

Kinetic Energy = 2750 kg * m^2/s^2

Therefore, Mr. Mabis would have 2750 joules of kinetic energy when he crashed into the overhead cart.
