SUMMARY
The coefficient of friction for a body of mass 10 kg on a rough horizontal surface was determined through two scenarios involving different accelerations. Initially, the body accelerated at 5 m/s², and upon doubling the horizontal force, the acceleration increased to 18 m/s². The calculations using the equations of motion and friction led to the conclusion that the coefficient of friction is 0.4, corresponding to option C.
