Textbook Question
Chapter 4, Problem 66P
You’re asked to calibrate a device used to measure vertical acceleration in helicopters. The device consists of a mass m hanging from a massless spring of constant k. Your job is to express the acceleration as a function of the position y of the mass relative to where it is when there’s no acceleration. Take the positive y-axis to point upward.

The coefficient of friction between m2 and the wall is u. There is no friction between the blocks and no friction between m1 and the wall.

- A particle, which remains at rest, is acted on by three forces R, S and T. The force R has magnitude 32 N and is directed vertically downwards. The force S is directed to the left and up at 55◦ to the horizontal. The force T is directed to the right and up at 42◦ to the horizontal.
