Answer

Explanation:

Step1: Calculate mechanical energy of Object A

Mechanical energy = Kinetic energy + Potential energy. For Object A, mechanical energy $E_A=604 + 285=889$ J.

Step2: Calculate mechanical energy of Object B

For Object B, mechanical energy $E_B=481+300 = 781$ J.

Step3: Compare mechanical energies

Since $889>781$, Object A has more mechanical energy.

Answer:

Object A has more mechanical energy.
