Recently stumbled on this problem:
A uniform disk (I =½ MR2
) of mass 8.0 kg can rotate without
friction on a fixed axis. A string is wrapped around its
circumference and is attached to a 6.0 kg mass. The string does
not slip. What is the tension in the cord while the mass is
falling?
The answer is 24 Newtons, but i would like to know why.
If anyone can provide a solution/explanation, that would be greatly appreciated.
I am having trouble figuring out the effect the disk's inertia has on the system's acceleration.
