sort of i was using a=F/m F=m2g->12*9.80=118 m=12kg + 8kg a=5.9 but its not one of the choices which are: a. 3.5 b. 3.9 c. 2.5 d. less than 2.5 e. cannot be determined

[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 can't 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...

thanks for the input and the diagram everybody.

A hole punch has a diameter of 8mm and presses onto 10 sheets of paper with force of 6.7kN. IF each sheet of paper is of thickness .2mm, find the shear stress. [HINT: Be careful in decing what area to use. Remember that a shear force acts parallel to the surface whose area is relavant.]...

nope just that. I am guessing it might be sufficient just to have the relationship i'm assuming g= 9.80 ?

Using this site as a reference: http://hyperphysics.phy-astr.gsu.edu/hbase/atwd.html Can somebody show me how to solve this: Suppose you don't have a watch, or a timer, and you want to use an Atwood's machine as a timer to give an accurate time interval (for the vertical fall) of t =...
