My bad. I confused translational with horizontal translational.

The drop of the slab releases potential energy which enhances kinetic energy. The perpendicular component of the slab displacement...

I would try some math. 1. I observe that angle ##\alpha## does not change during the motion but the slab moves with NOT purely...

Thank you very much @anuttarasammyak, you've solved every doubt.

Because by ##\lambda## you got $$ f_r=\frac{v}{\lambda} $$ 0.86 m is for ##u_s=0##, a parked car, which is larger than 0.76m which is...

If B performs a measurement, there is no doubt that this constitutes an event. However, in the situation under consideration, B does not...

By the hint $$<L_x>=<L_y>=0$$ $$<L_z>=l\hbar$$

Here, I assume that all inertial frames agree that the collapse occurs when the reading of clock B is the smallest, namely at T−L/c...

The first law of thermodynamics : dU=dQ-dW Energy can be supplied not only as work dW, which may originate from conservative forces, but...

What path dependency do you find in this case? I am not sure of it.
