Aparticle moves along a circular path over a horizontal xy coordinate system, at constant speed. at time t1 = 4.50 s, it is at point (5.80 m, 5.60 m) with velocity (3.50 m/s) j and acceleration in the positive x direction. at time t2 = 11.7 s, it has velocity (–3.50 m/s) i and acceleration in the positive y direction. what are the (a) x and (b) y coordinates of the center of the circular path? assume at both times that the particle is on the same orbit.

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?
