1. The problem statement, all variables and given/known data Two objects are made of identical material and are tied together with string. The first object has a mass of 5.0kg and the second object has a mass of 3.0kg. Students measure the maximum force of static friction as 31.4N to move both objects across a horizontal surface. a) What is the coefficient of static friction? b) What is the magnitude of the tension in the string if they pull on the first object? c) A student pushes the 3.0kg object with a force of 15.0[down]. What are the magnitudes of the maximum force of static friction and the tension now? d) Will your answers to (c) change if the student pushes down on the 5.0kg object instead? Explain. 2. Relevant equations 3. The attempt at a solution a) μs=Fs / Fn =31.4 / (8)(9.8) μs= 0.40 b) To solve B) I came up with two equations, one for each object and equated them to solve for acceleration, and tension. Fs-Ft=ma 31.4-Ft=5a Ft=31.4-5a Ft= 11.78N <-- I found this by finding the acceleration first, and subbing it into 31.4-5a Ft=ma 31.4-5a=3a 31.4=8a a=2.925m/s2 c) d) I know how to solve a) b) but I have no clue how to solve c). How would I go about doing it?
