They have the same amount of energy.
Object A
To determine which object has more kinetic energy, we need to use the formula for kinetic energy:
Kinetic energy = (1/2) × mass × velocity^2
For Object A:
Mass = 10 kg
Velocity = 10 m/s
Kinetic energy of Object A = (1/2) × 10 kg × (10 m/s)^2 = 500 J
For Object B:
Mass = 10 kg
Velocity = 5 m/s
Kinetic energy of Object B = (1/2) × 10 kg × (5 m/s)^2 = 125 J
Comparing the kinetic energies of Object A and Object B, we find that Object A has more kinetic energy with 500 J, while Object B has 125 J. Therefore, the correct answer is: Object A has more kinetic energy.
To determine which object has more kinetic energy, we can use the formula for kinetic energy: KE = 1/2 * m * v^2, where KE is the kinetic energy, m is the mass of the object, and v is the velocity or speed of the object.
For Object A:
Mass (m) = 10 kg
Speed (v) = 10 m/s
For Object B:
Mass (m) = 10 kg
Speed (v) = 5 m/s
Now we can calculate the kinetic energy for each object:
Kinetic Energy of Object A:
KE = 1/2 * 10 kg * (10 m/s)^2 = 500 J
Kinetic Energy of Object B:
KE = 1/2 * 10 kg * (5 m/s)^2 = 125 J
Comparing the calculated values, we can see that Object A has a higher kinetic energy of 500 J, while Object B has a lower kinetic energy of 125 J.
Therefore, the correct answer is: Object A has more kinetic energy than Object B.
