Quizplus · Accepted Answer

The acceleration of the system can be calculated using Newton's second law and considering the forces acting on both masses, including the force of gravity, tension, and friction. The tension in the string is determined by the force needed to accelerate both masses. Given the coefficient of friction and the masses, the correct calculations lead to an acceleration of 5.2 m/s^2 and a tension of 92 N.
