Kinetic energy is the energy of an object in motion. The formula k= 1/2 mc2 is used to calculate kinetic energy. The variable m is an objects mass, and g is its velocity. Calculate the kinetic energy of a 45 kilogram object traveling at 3 meters per second. Your awnser will be in Joules.
To calculate the kinetic energy (K) using the formula K = 1/2 * m * g^2, we need to know the velocity (v) of the object, not the mass (m). Considering that there might be a typo in the question and the velocity is actually referred to as "g", we can calculate the kinetic energy.
Using the correct formula K = 1/2 * m * v^2, where m = 45 kg and v = 3 m/s, we can substitute these values into the formula:
K = 1/2 * (45 kg) * (3 m/s)^2
K = 1/2 * 45 kg * 9 m^2/s^2
K = 1/2 * 45 kg * 9 m^2/s^2
K = 2025 J
Therefore, the kinetic energy of the 45 kg object traveling at 3 m/s is 2025 Joules.
