800 g 400 g 82. An 800 g block lies on a horizontal tabletop. The friction between the table and the block is negligible. The block is connected by a massless string to the second block with a mass of 400 g. The string passes over a light frictionless pulley as shown above. The system is released from rest. a. Draw clearly labeled free-body diagrams for each of the 800 g and the 400g masses. Include all forces and draw them to relative scale. Draw the expected direction of acceleration next to each free-body diagram. b. Use Newton's Second Law to write an equation for the 800 g mass. c. Use Newton's Second Law to write an equation for the 400 g mass. d. Find the acceleration of the system by simultaneously solving the system of two equations. What is the tension force in the string
