SUMMARY
The work calculation for overcoming friction in the discussed scenario is incorrect. The applied force of 52 N on a 12 kg mass results in a net force of 37 N when accounting for the 15 N friction force. The correct work done to overcome friction while moving the object 24 m is calculated as 24 m multiplied by the friction force of 15 N, resulting in 360 J. Therefore, the work done to overcome friction is -360 J, reflecting the energy required to maintain constant velocity against friction.
