The formula for kinetic energy (KE) is KE = 1/2 * mass * velocity^2.
Calculating the kinetic energy for the first object:
KE1 = 1/2 * 5kg * (10 m/s)^2
KE1 = 1/2 * 5kg * 100 m^2/s^2
KE1 = 250 Joules
Calculating the kinetic energy for the second object:
KE2 = 1/2 * 10kg * (5 m/s)^2
KE2 = 1/2 * 10kg * 25 m^2/s^2
KE2 = 125 Joules
Comparing the values, we find that the first object with a mass of 5kg and a speed of 10 m/s has a higher kinetic energy of 250 Joules.
As shown below, an object with a mass of 5kg is moving at a speed of 10 m/s. another object with the mass of 10kg is moving at the speed of 5 m/s.
