[URGENT] Acceleration Problem due to Rotational Inertia [Exam in 9hrs!] yes i know i might be late but i hope somebody can help me out with this problem because i cant figure it out. Exact word for word: A block of mass m2= 12kg hangs from a rope. The rope wraps around a pulley and then attaches to a second block of mass m1=8kg, which sits on a frictionless table. The radius of the pulley is .10m and its rotational inertia is I=.040 kg-m2. What is the acceleration of the blocks when they are released. here is how it looks: http://spiff.rit.edu/classes/phys311/workshops/w5b/level_atwood/cart_and_weight.gif a modified atwood machine.
