Answer:

The kinetic energy of a moving object can be calculated using the formula: Kinetic energy = 0.5 * mass * velocity^2 Given that the mass of the object is 10 kg and the velocity is 4 m/s, we can substitute these values into the formula to find the kinetic energy. Kinetic energy = 0.5 * 10 kg * (4 m/s)^2 Kinetic energy = 0.5 * 10 kg * 16 m^2/s^2 Kinetic energy = 80 J Therefore, the kinetic energy of a 10 kg object moving at 4 m/s is 80 J (joules).
