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?
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.
