A 500 g block lies on a horizontal tabletop. The coefficient of kinetic friction between the block and the surface is 0.25. The block is connected by a massless string to the second block with a mass of 300 g.
The string passes over a light frictionless pulley as shown above. The system is released from rest.
Find the acceleration of the system by simultaneously solving the system of two equations.
What is the tension force in the string?
