1. The problem statement, all variables and given/known data The system shown in the diagram is accelerating toward the right (clockwise). Find the acceleration in terms of m1, m2, m3, uk, and g. Note: There aren't any numbers used in this problem. It's just working with the variables to create an expression equal to the acceleration. 2. Relevant equations Fg = mg Ff = ukFn SumofF= ma 3. The attempt at a solution I began by creating free body diagrams of each mass, starting with m3. I used the forumla Fg = mg to get m3g. This is also equal to the tension in the string. T = m3g I moved on to creating a free body diagram of mass2. I used the forumla Fg=mg, where this downward force would be equal to the normal force. I then used the equation Ff = ukFn to get the friction force. Subtracting this friction force from the tension in the string would give me the net force for m2. T = m3g - m2guk This force would be equal to the tension in the string pulling m1 which is m3g - m2guk. Because the system is moving clockwise I subtract m1g to get the sum of all the sytem's forces moving in the clockwise direction. F = m3g - m2guk - m1g Since I need to find the acceleration of the system, I set the expression m3g - m2guk - m1g equal to m1, because m3g - m2guk - m1g is the force pulling m1 up. Thus. (m3g - m2guk - m1g) / (m1) = a Did I solve this problem correctly or was there some flaw to the logic I used? Thanks ahead of time. I apologize for the quality of the diagrams.
