block 3M slides downward without friction. The string connecting blocks 3M and M is ideal (that is, its mass can be neglected and it is not stretchable). The pulley, a uniform solid disc of mass M and radius r , rotates without slipping. Find the acceleration of block 3M.

After the velocity selector, a mass spectrometer allows the charged particle to enter a region of magnetic field only, where it follows a curved trajectory and hits a detector which records his position. Your mass spectrometer has the velocity selector set for 2.39 x 10^5 m/s ...
