The kinetic energy of an object is given by the formula:
Kinetic energy = 1/2 * mass * velocity^2
Let's calculate the kinetic energy of both objects:
For the first object:
Mass = 5 kg
Velocity = 10 m/s
Kinetic energy = 1/2 * 5 kg * (10 m/s)^2 = 250 J
For the second object:
Mass = 10 kg
Velocity = 5 m/s
Kinetic energy = 1/2 * 10 kg * (5 m/s)^2 = 125 J
Therefore, the first object with a mass of 5 kg and a speed of 10 m/s has a higher kinetic energy of 250 J.
