Question

8 can't be c and 9 can't be D....

What would happened to the slope of Applied Force vs. Acceleration for an Atwood's Machine just like the one we used in lab, if the total system mass was increased? The slope would have increased because the slope represents the total system mass. The slope would have stayed the same because the force required and acceleration measured would change proportionally, leaving a slope the same as before. The slope would increase because the slope represents the friction in the bearings; and that would increase. The slope would decrease because the same force would give rise to less acceleration thus reducing the slope of F vs. a. The slope would have increased because it would required less force to obtain the same accelerations. What would happened to the vertical intercept of Applied Force vs. Acceleration for an Atwood's Machine just like the one we used in lab, if the total system mass was increased? The vertical intercept would have decreased because it would have required less force to move the system with the same acceleration. The vertical intercept would have increased because the vertical intercept represents the total mass of the system. The vertical intercept would have increased because the friction in the bearings would have been more due to more load on the bearings. The vertical intercept would have increased because the difference in masses would have been bigger thus requiring more applied force to move the system. The vertical intercept would have decreased because the friction in the bearings would be diminished due to efficiency of loading.
