Un pasager a întârziat la tren. Ajuns pe peron a observat trenul în mişcare şi a constatat că unul din vagoane a trecut prin
faţa sa în intervalul de timp t1=6,6s, iar vagonul al doilea în
23
t2=6,0s. Considerând mişcarea trenului rectilinie uniform
accelerată, să se determine:
a) intervalul de timp τ cu care a întârziat pasagerul;
b) intervalul de timp t3 în care prin faţa sa trece vagonul
următor.

Aparticle of mass m is placed in a one-dimensional box of length l. the box is so small that the particle’s motion is relativistic, so that e p2/2m is not valid. (a) derive an expression for the energy levels of the particle using the relativistic energy–momentum relation and the quantization of momentum that derives from connement. (b) if the particle is an electron in a box of length l 1.00 1012 m, nd its lowest possible kinetic energy. by what percent is the nonrelativistic formula for the energy in error?
