Answer

65 J\text{65 J}

Step-by-step solution

4 steps

  1. Apply the Work-Energy Theorem.

    The work-energy theorem states that the net work done on an object is equal to the change in its kinetic energy.

    W=ΔKE=KEfinal−KEinitialW = \Delta KE = KE_{final} - KE_{initial}

  2. Identify the given values.

    Initial kinetic energy (KEinitialKE_{initial}) = 65 J65 \text{ J}
    Final kinetic energy (KEfinalKE_{final}) = 130 J130 \text{ J}

  3. Substitute the values into the formula.

    W=130 J−65 JW = 130 \text{ J} - 65 \text{ J}

  4. Calculate the work done.

    W=65 JW = 65 \text{ J}
