Part D: Thinking [14] 1. Two blocks connected by a string are pulled across a horizontal surface as shown below. The coefficient of kinetic friction between the blocks and the surface is 0.25. If the applied force acting at an angle of 60 to the horizontal is 24.85 N, calculate a) the acceleration of the system b) tension in the string Show all your work including free-body diagrams and formulas. 60 3.0 kg 1.0 kg
